Abstract

A 1.4-GHz LC voltage-controlled oscillator has been implemented in a MOSIS 0.5-µm CMOS process. Complementary cross-coupled PMOS and NMOS transistors enhance single-ended symmetry at each of the resonant nodes, reducing close-in phase noise. Tapped bond wires provide a resonant tank with high Q. At an offset frequency of 100 kHz, the measured phase noise is -107 dBc/Hz with 3 mW power dissipation from a 3.0 V supply. NMOS gate capacitors achieve a 17% tuning range.
