A new low-phase noise low-power quadrature voltage-controlled oscillator (QVCO) using differential Colpitts oscillator is presented. The proposed QVCO is composed of two identical current-switching differential Colpitts VCOs in which the first core...

A study of some reported superharmonic LC quadrature voltage-controlled oscillator (LC-QVCO) is performed in which it is shown that robustness of the quadrature oscillation varies depending on the coupling configuration. ...
