A 1.6 GHz 0.5 mW CMOS LC Low Phase Noise VCO Using Bond Wire Inductance
نویسندگان
چکیده
A 1.6-GHz LC voltage-controlled oscillator has been implemented in a 0.5-μm CMOS process. Bond wires, with their low series resistance, provide a resonant tank with high Q. Complementary crosscoupled PMOS and NMOS transistors enhance the single-ended symmetry at each of the resonant nodes to reduce close-in phase noise. At an offset frequency of 100 kHz, the measured phase noise is -95 dBc/Hz at a 0.5 mW power dissipation from a 2.0 V supply. An 8.7% tuning range is achieved using NMOS gate capacitors.
