ABSTRACT:
An interface circuit provided between a compound semiconductor logic circuit and a bipolar transistor circuit includes an input buffer part for receiving an input signal from the GaAs logic circuit and for outputting a buffered input signal, and an output driver circuit for generating a drive signal from the buffered input signal. The interface circuit also includes an output transistor having a gate connectable to receive the drive signal, a first terminal connectable to receive a first power supply voltage, and a second terminal, and an output terminal connected to the second terminal of the output transistor and the bipolar transistor circuit. Further, the interface circuit includes an output level adjustment circuit which has a first Schottky barrier transistor having a gate, a first terminal connected to the gate of the Schottky barrier transistor and the gate of the output transistor, and a second terminal and which generates a constant voltage applied to the second terminal of the Schottky barrier transistor.
