Impact of mutual inductance and parasitic capacitance on the phase-error performance of CMOS quadrature VCOs
Publikation/Tidskrift/Serie: Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03.
This paper examines the impact of mutual inductance and parasitic capacitance on the phase-error performance for a class of CMOS quadrature voltage-controlled oscillators (QVCOs). Good agreement is found between theory, post-layout simulations, and measurement results. The QVCOs were implemented in a standard 0.35/spl mu/m CMOS process. All QVCOs display a center frequency of 2 GHz and a tuning range of 15%.
