Circuit for generating very small currents

摘要

The relationship of a reference current of a current balancing circuit to a first output current at the collector of an output transistor is adjusted via the dimensioning of a first resistance R in the emitter of the output transistor of a current balancing circuit. By adding a second current balancing circuit with a second resistor R' contained therein and which provides a second output current, there results, for R=R', the relationship of the first output current to the second output current corresponding to the relationship of the reference current to the first output current.
