Abstract :
An accurate 1.08-GHz CMOS LC voltage-controlled oscillator is implemented in a 0.35μm standard 2P4M CMOS process. In this paper we present a new convenient method of calculation of oscillating period. With this period calculation technique, the frequency tuning curves agree perfectly with the experiment. At a 3.3-V supply, the LC-VCO measures a phase noise of 82.2 dBc/Hz at a 10 kHz frequency offset while dissipating 3.1mA current. Chip size is 0.86mm × 0.82mm.
