This paper describes how a novel low phase noise
Figure of Merit (FOM), LC-tank voltage-controlled oscillator
(VCO) is presented. The work presents a fully integrated 5.0
GHz VCO designed in a 0.35µm CMOS process. The proposed
VCO features a worst-case phase noise of -133.07 dBc/Hz and
136.31 dBc/Hz at 600 kHz and 1 MHz frequency offset. An
optimization technique is used to design the excellent FOM.
The FOM is -206. 20 dBc/Hz. It features a supply of 2.4 V, a
core of only 1.0 mA.
