Anhand der Zeichnung wird die Erfindung näher erläutert Es zeigtThe invention is explained in more detail with the aid of the drawing

Fig.4 eine Stromquelle mit einer Kompensationsschaltung, die als Kompensationselement eine Diode enthält.4 shows a current source with a compensation circuit which, as a compensation element, uses a diode contains.
Bei den Ausfflhrungsbeispielen nach den F i g. 1 bis 3 ist ein Stromquellen-NPN-Transistor 70 mit seinem Emitter an den Minuspol 2 einer Spannungsquelle angeschlossen. Hierbei wird davon ausgegangen, daß der Wannen-Reststrom 73, der in die Substratdiode 72 des Stromquellen-N PN-Transistors 70 fließt und einen unerwünschten Beitrag zum Ausgangsstrom 71 liefert, direkt am Kollektor des Transistors 70 kompensiert werden muß. Dies erreicht man bei diesen Ausführungsbeispielen durch eine Kompensationsschaltung, die einen aus Restströmen der Kompensationselemente gewonnenen Kompensationsstrom 74 liefert, der annähernd gleich dem störenden Wannen-Reststrom 73 ist.In the exemplary embodiments according to FIGS. 1 to 3, a current source NPN transistor 70 is connected with its emitter to the negative pole 2 of a voltage source. It is assumed here that the residual well current 73, which flows into the substrate diode 72 of the current source N PN transistor 70 and makes an undesirable contribution to the output current 71, must be compensated directly at the collector of the transistor 70. In these exemplary embodiments, this is achieved by means of a compensation circuit which supplies a compensation current 74 obtained from residual currents of the compensation elements, which is approximately equal to the disturbing tub residual current 73.
Die Kompensationsschaltung enthält gemäß F i g. 1 einen einzigen lateralen PNP-Transistor 76, dessen Emitter galvanisch mit dem Pluspol 4 der Spannungsquelle verbunden ist. Der Lateraltransistor 76 besitzt zwei Kollektoren, von denen der erste an den Kollektor des NPN-Transistors 70 angeschlossen ist. Der zweite Kollektor und die Basis des lateralen PNP-Transistors 76 sind aneinander angeschlossen. Dadurch wird erreicht, daß der Einfluß der Stromverstärkung, die starken Fertigungsschwankungen unterliegt, stark reduziert wird. Wenn beide Kollektoren des Lateraltransistors 76 gleich groß sind, liegt die Stromverstärkung der gegengekoppelten Anordnung etwas unter I und ist relativ konstant, so daß in vielen Fällen eine ausreichende Kompensation des Wannenstromes 73 durch den Wannenstrom 77 erreicht wird, wenn beide Wannen gleich groß gemacht werden.The compensation circuit contains according to FIG. 1 a single lateral PNP transistor 76, the The emitter is galvanically connected to the positive pole 4 of the voltage source. The lateral transistor 76 has two collectors, the first of which is connected to the collector of the NPN transistor 70. The second The collector and the base of the lateral PNP transistor 76 are connected to each other. This will achieves that the influence of the current amplification, which is subject to strong manufacturing fluctuations, is greatly reduced. If both collectors of the lateral transistor 76 are the same size, the current gain is the negative feedback arrangement slightly below I and is relatively constant, so that in many cases a Sufficient compensation of the tub flow 73 by the tub flow 77 is achieved if both Tubs can be made the same size.
Nahezu vollständig läßt sich der Einfluß der Stromverstärkung des Lateraltransistors 76 elemitiieren, wenn man gemäß Fig. 2 einen gut verstärkenden PNP-Transistor 78, vorzugsweise einen vertikalen Substrattransistor, in die Gegenkopplungsschleife einfügt. Wenn in dieser Anordnung der Wannenstrom 77 des Lateraltransistors 76 fehlen würde, wäre der Kompensationsstrom 74 recht genau gleich dem Wannenstrom 79, der in die Substratdiode 80 desThe influence of the current amplification of the lateral transistor 76 can be eliminated almost completely if, as shown in FIG PNP transistor 78, preferably a vertical substrate transistor, inserts into the negative feedback loop. If in this arrangement the tub flow 77 of the lateral transistor 76 would be absent, the compensation current 74 would be quite exactly the same Well current 79 flowing into the substrate diode 80 of the PNP-Transistors 78 fließt. Zur genauen Kompensation des Wannenstromes 73 des Stromquellentransistors 70 müßte man nur noch die Wanne des PNP-Transistors 78 so g.-oß machen wie diejenige des Transistors 70. s Der Wannenstrom 77, der durch die Substratdiode 75 des Lateraltransistors 76 fließt, stört indessen noch die genaue Bilanz der Restströme; außerdem kann er so groß werden, daß vom Basisstrom des Lateraltransistors 76 nichts mehr für den Emitterstrom desPNP transistor 78 flows. For exact compensation of the well current 73 of the current source transistor 70 one would only need the well of the PNP transistor 78 make as g.-oß as that of transistor 70. The well current 77 which flows through the substrate diode 75 of the lateral transistor 76, however, still disturbs the exact balance of the residual flows; In addition, it can be so large that nothing of the base current of the lateral transistor 76 is used for the emitter current of the
ίο PNP-Transistors 78 übrigbleibt, so daß der Transistor 78 sperren kann.ίο PNP transistor 78 remains, so that transistor 78 can lock.
Diese Schwierigkeit behebt man nach F i g. 3 durch einen weiteren lateralen PNP-Transistor 81, der zu Kompensation des noch störenden Wannenstromes 77This difficulty is eliminated according to FIG. 3 by a further lateral PNP transistor 81, the to Compensation of the still disruptive tub flow 77
rs den verstärkten Wannenstrom 82, der in seine Substratdiode 83 fließt, liefert und damit auch den Emitterstrom für den PNP-Transistor 78 sicherstellt. Der Lateraltransistor 81 liefert außerdem einen Kollektor-Emitter-Reststrom, der in guter Näherungrs the reinforced tub stream 82 that flows into his Substrate diode 83 flows, supplies and thus also ensures the emitter current for PNP transistor 78. The lateral transistor 81 also supplies a collector-emitter residual current, which is a good approximation
zo den Kollektor-Emitter-Reststrom des Lateraltransistors 76 kompensiert. Der Kompensationsstrom 74 ist also beim Ausführungsbeispiel nach Fig.3 recht genau gleich dem Wannenstrom 79 des PNP-Transistors 78. Macht man dessen Wanne gleich groß wie die Wanne zo compensates the collector-emitter residual current of the lateral transistor 76. The compensation current 74 in the exemplary embodiment according to FIG. 3 is therefore exactly the same as the tub current 79 of the PNP transistor 78. If the tub is made the same size as the tub des Stromquellen-Transistors 70, so ist damit der Wannenstrom 73 dieses Transistors recht genau kompensiert.of the current source transistor 70, the well current 73 of this transistor is therefore quite accurate compensated.
Als weiteres Ausführungsbeispiel ist in F i g. 4 eine steuerbare Stromquelle dargestellt, deren AusgangsAs a further exemplary embodiment, FIG. 4 shows a controllable current source, the output of which strom 60 sehr genau und relativ klein sein soll. Wenn der in Fig.4 dargestellte Operationsverstärker 64 ideale Eigenschaften besitzt, liegt die steuernde Spannung 62 auch am Emitterwiderstand 63 der Stromquelle. Wenn außerdem der NPN-Transistor 61, der auch durch einecurrent 60 should be very precise and relatively small. If the Operational amplifier 64 illustrated in FIG. 4 is ideal Has properties, the controlling voltage 62 is also applied to the emitter resistor 63 of the current source. if also the NPN transistor 61, which is also through a Darlington-Schaltung ersetzt werden kann, eine sehr hohe Stromverstärkung besitzt, ist der Ausgangsstrom 60 gleich der Spannung 62 geteilt durch den Widerstand 63. Bei höheren Temperaturen liefert jedoch der Wannenstrom 65, der in die Substratdiode 66 desDarlington pair can be replaced, a very has high current gain, the output current 60 is equal to the voltage 62 divided by the resistance 63. At higher temperatures, however, the well current 65, which is fed into the substrate diode 66 of the Transistors 61 fließt, einen unerwünschten Beitrag zum Ausgangsstrom 60. Dieser wird nun erfindungsgemäß durch den Wannenstrom 67 einer zusätzlichen, kathodenseitig mit dem nicht invertierenden Eingang des Operationsverstärkers 64 verbundenen SubstratdiodeTransistor 61 flows, an undesirable contribution to output current 60. This is now according to the invention through the well current 67 an additional, cathode side with the non-inverting input of the Operational amplifier 64 connected substrate diode 68 kompensiert, deren Wanne dieselbe Größe hat wie die Wanne des Transistors 61. Die Wannenströme 65 und 67 sind dann über einen großen Temperaturbereich hinweg einander annähernd gleich. Fügt man nun zwischen den nicht invertierenden Eingang des68 compensated whose tub is the same size as the well of transistor 61. Well currents 65 and 67 are then over a wide temperature range almost equal to each other. If you now add between the non-inverting input of the Operationsverstärkers 64 und die Spannungsquelle 62 einen Widerstand 69, der gleich dem Emitterwiderstand 63 ist, ein, so wird die Spannung am Widerstand 63 durch den Spannungsabfali, den der Wannenstrom 67 am Widerstand 69 hervorruft, gerade um denjenigenOperational amplifier 64 and the voltage source 62 have a resistor 69, which is equal to the emitter resistance 63 is on, the voltage across resistor 63 is determined by the voltage drop caused by well current 67 at the resistor 69 evokes, just about that one Betrag abgesenkt, der den Ausgangsstrom 60 auf den Wert bringt, als ob der Wannenstrom 65 nicht fließen würde.Reduced amount that the output current 60 to the Brings value as if the well current 65 were not flowing.
