Abstract :
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 a good phase noise characteristic. The developed theory matches very well to the simulations.
