ABSTRACT:
A level converter circuit includes a differential amplifier 20 having a load resistor 8 supplied at its one end with a voltage which is stabilized against the variation of a power voltage by an emitter-follower transistor 4 receiving at its base a bias voltage from a bias circuit 9, 12-14. An intermediate signal is derived from the other end of the load resistor and supplied to a level shift circuit 25.
