Amplitude detection inside CMOS LC oscillators

In this paper we demonstrate that an intrinsic amplitude detector exists in negative resistance CMOS LC oscillators. The DC bias on the common-mode node in CMOS VCOs depends on the oscillation amplitude. Amplitude control loops can thus be built without a separate amplitude detector. Insights in possible AM to PM noise mechanisms are also derived
