Abstract: Three-transistor, four-terminal precision current source is switchable. Current is passed between two of the terminals in the presence of a switching signal on another terminal. While switched on, the current is regulated according to a reference voltage supplied to the remaining terminal.The drawing shows four similar, parallel circuits supplying current from a source +V to a light emitting diode 17. Each circuit comprises an output transistor 10 which draws current through resistor 16. The current carrying capacity of transistor 10 is controlled by two emitter coupled, complementary transistors 11, 12. The signal V(REF) supplied to transistor 11 determines the conductivity of that transistor and the signal supplied to transistor 12 renders that transistor OFF or ON and operating in the saturation region. The base current to transistor 10 is therefore controlled to be ON or OFF via transistor 12 and its magnitude when ON is controlled via transistor 11.
