ABSTRACT:
An output amplitude regulating circuit comprises a first MOS differential circuit, with a first MOS transistor connected between an output terminal of the first MOS differential circuit and a power supply. The circuit also includes a second MOS differential circuit having a first input terminal that receives a reference electric potential, and a second MOS transistor that is connected between the power supply and a second input terminal of the second MOS differential circuit, and is connected to a reference electric potential via a third MOS transistor and a current source. In the circuit, output terminals of the first and second MOS transistors are used to regulate an output amplitude from the output terminal of the first MOS differential circuit.
