Phase noise reduction in RF CMOS VCO's via capacitive filtering

Andreani, Pietro LU (2001) In Proceedings of the NORCHIP '01 Conference. p.21-27
Abstract
This paper presents the experimental results of two different techniques, the

already known inductive degeneration technique and the new capacitive filtering

technique, for reducing the phase noise in RF CMOS VCO's. The techniques are

applied to two distinct VCO designs, showing that the largest phase noise reduction

(up to 7 dB at 3 MHz offset frequency from the carrier) is achieved via inductive

degeneration. Capacitive filtering, however, also substantially reduces the phase

noise, and may therefore become a valid alternative to inductive degeneration, as

discrete capacitors are of more common use than discrete inductors.
