Abstract :
VCO for wireless receivers must fulfil tight requirements of phase noise and their complete integration in silicon VLSI technologies is still an open issue due to the low quality factor of the inductors. In this paper we address some of the constraints met in the design of low noise oscillator stages: the tank topology and its quality factor, the dynamics of the transconductor stage and its loading effects, the limitation resulting from the AM-to-PM conversion
