Abstract
PURPOSE: To measure the input bias currents of a balance type amplifier with differential input terminals and complementary symmetry output terminals accurately by a method wherein negative feedback of two systems is provided among the complementary symmetry output terminals and the differential input terminals.
CONSTITUTION: A negative feedback circuit 2 is formed by connecting an input terminal II and an output terminal ON having an input and output transmitting characteristic of an antiphase of a balance type amplifier 1 with differential input terminals II, IN and complementary symmetry output terminals OI, ON, and a negative feedback circuit 3 is made up by similarly connecting the input terminal IN and the output terminal OI having an input and output characteristic of the antiphase. A switch SW1 is turned OFF and a switch SW2 is turned ON and differential voltage between the complementary symmetry output terminals is measured, the switches are reversed and the differential voltage is measured, and input bias currents are obtained from these values. Thus, the input bias currents can accurately be measured because great voltage between the complementary symmetry output terminals is measured.
