Abstract

PURPOSE: To keep a high impedance at all times in high speed and to obtain normal operation, by connecting the base of a compensating transistor (TR) to each base of a current Miller circuit, in an input circuit of a comparator of a complementary connection.
CONSTITUTION: A compensation transistor (TR)14 is formed in the shape in the same chip as TRs 3, 4 and thus, the base current IB2 is made equal to the base current IB2 of the Trs 3, 4 by supplying a current I0 to the emitter of the TR14. The sink current of TRs 11, 12 is IB2 respectively with the current Miller circuit in the base current IB2 of the TR14, and the total sink current from points A and B is respectively I1+IB2, allowing to set each emitter current of TRs 1, 2 to a given value I1.
