Filed: 1991-04-26
Abstract: PURPOSE:To reduce phase noise by using a GaAsMESFET of pulse dope structure and employing a variable capacitor whose capacitance is increased when a gate bias voltage of the FET is changed in a direction of drain current increase for a series feedback capacitor. CONSTITUTION:According to the simulation, when the oscillation circuit is formed by employing a GaAsMESFET1 of pulse dope structure whose gate length is 0.5mum and whose gate width is 280mum, the required series feedback capacitance is 0.17pF with a bias to obtain a drain current of 24mA and 0.2pF with the drain current of 50mA with respect to the oscillating frequency of 10.7GHz. That is, when a gate bias of the FET1 is changed in a direction of drain current increase, the required series feedback capacitance for the oscillation at a desired frequency is increased. Thus, a varactor diode is employed for the series feedback capacitor 2 and phase noise is reduced while keeping the oscillating frequency constant.
