Abstract:
A Colpitts oscillator includes a tank circuit, a first transistor, and a first feedback circuit. The first transistor includes a first region, a second region, and a control region. The first region communicates with the tank circuit. The first feedback circuit communicates with the second region and the control region of the first transistor.
