Patent ID: 7443256

Claim:
An oscillator circuit, comprising: an oscillation unit for outputting a first oscillation signal; a voltage control unit including first and second control elements having source terminals that are connected to each other; and an output unit including first and second output control elements, arranged between first and second output current sources, and a first output terminal arranged at a connection node between the first and second output control elements, wherein: the first control element has a drain terminal connected to a connection node between the first output current source and the first output control element; the second control element has a drain terminal connected to a connection node between the second output control element and the second output current source; a connection node between the source terminal of the first control element and the source terminal of the second control element is connected so as to receive the first oscillation signal from the oscillation unit; and the first control element has a gate terminal for receiving a predetermined bias, and the second control element has a gate terminal for receiving a reference voltage for determining an amplitude of an oscillation signal.
