Abstract
An oscillator circuit for increasing the signal power of a generated oscillating signal while decreasing phase noise. The circuit includes an oscillating stage having an inductor and capacitors for producing a periodic oscillating signal and a first control signal. An active stage having a transistor with a gate terminal, a source terminal and a drain terminal is connected to the oscillating stage so that the first control signal is provided to the source terminal of the transistor. A second control signal is provided to the transistor gate terminal for increasing the voltage applied to the gate terminal when the first control signal decreases the voltage applied to the source terminal, thus controlling the activation of the transistor for supplying signal boosting power to the tank stage.
