Abstract
A buffer circuit includes a main buffer circuit section formed of a pair of complementary input side transistors the bases of which are connected together to an input, a dummy circuit section having the same circuit construction as the main buffer circuit section, and a feedback signal section compares the output from the dummy circuit section with a predetermined value to provide a feedback signal which is supplied to the dummy circuit section and the main buffer circuit section so as to make the output of the dummy circuit section equal to that predetermined value.
