Abstract:
1. An oscillator having a negative resistance device and a resonator and comprising: a transmission line connected to the negative resistance device; a three-terminal device including: a first terminal connected to the signal line side of the transmission line at a terminal part of the transmission line; a second terminal connected to the grounding line side of the transmission line; and a third terminal for receiving a control signal to be applied thereto; a first regulation unit for regulating the control signal to be applied to the third terminal of the three-terminal device; and a second regulation unit for regulating voltage to be applied to the second terminal, the first regulation unit and the second regulation unit being adapted to regulate respectively the control signal and the voltage so as to make the characteristic impedance of the transmission line and the impedance between the first terminal and the second terminal of the three-terminal device show an impedance matching.
