ABSTRACT:
A signal converting circuit for converting a single-ended input signal to a pair of differential output signals includes a current source for generating a constant current; an input signal generating circuit for generating an input signal current; a first path including at least one diode connected to the current source and the input signal generating circuit for producing a first differential current as a function of the constant current and the input signal current; a second path including a series combination of a diode and the collector-emitter path of a transistor connected to the current source and the input signal generating circuit for producing a second differential current as a function of the constant current and the input signal current, the transistor being supplied with a current at its input; a differential amplifier output circuit having two transistors connected to the first and second paths for producing differential output signals in response to the first and second differential currents; and a circuit for eliminating the effect on the differential output signals of the current at the input of the transistor, the circuit for eliminating including a transistor having its collector-emitter path connected between the first path and ground and a diode connected between the second path and ground.
