Differential current distributing circuit.

摘要

A differential current distributing circuit includes a first current path including a first resistor (R1), collector-emitter path of a first transistor (TR3) of first conductivity type and emitter-collector path of second conductivity type which are connected in series between the output terminal of a constant current source (EI) and a first current output terminal (1) and a second current path including a second resistor (R2), collector-emitter path of a third transistor (TR4) of first conductivity type and emitter-coiiector path of a fourth transistor of second conductivity type which are connected in series between the output terminal of the constant current source and a second current output terminal (2). The base electrode of the first transistor (TR3) is connected to the output terminal of the second resistor and the base electrode of the third transistor (TR4) is connected to the output terminal of the first resistor. A first input signal (IN1) is supplied to the base electrode of the second transistor and a second input signal (IN2) is supplied to the base electrode of the fourth transistor.
