Bulk-source-coupled CMOS Quadrature Oscillators

Pierre-André Farine, Cyril Botteron, Uroschanit Yodprasit, Paul Saad

A quadrature oscillator based on a coupling between the bulk and the source of MOS transistors is proposed. Since the resonator load is not directly involved in the coupling process, the oscillation frequency is very close to the resonant frequency, hence ...

Common-mode Oscillation in Capacitive Coupled Differential Colpitts Oscillators

Christian Enz, Uroschanit Yodprasit

A simple approach to the realisation of a differential Colpitts oscillator is to connect the grounded capacitor in the feedback network of two single-ended Colpitts oscillators together in series. As the output signals are expected to be differential, it i ...
