Class-C oscillator

Abstract:

An oscillator operable in Class-C comprises at least one set of cross-coupled transistors. A threshold voltage of the transistors is controllable by having a bias voltage applied at back-gates of the transistors. The bias voltage thereby controls a conduction angle of the transistors to enable operation of the oscillator in Class-C. There is further provided a radio transceiver comprising such an oscillator, a method of operating such an oscillator, and a controller configured to operate such an oscillator.
