Abstract
A fully integrated low phase noise 4.6-GHz voltage-controlled oscillator (VCO) is presented for low-voltage high-frequency wireless local area network (LAN) front-end system applications. The VCO is based on a differential negative resistance oscillator with the tail current source replaced by an inductor. The inductor improves the phase noise of the oscillator and enables maximum voltage swing over the tank. A high-performance inductor with unclosed-loop guard ring is designed and used in this VCO design. The differential voltage-controlled oscillator is fabricated in a TSMC 0.18-µm one-poly-six-metal 1.5 V mixed signal radio frequency (RF) process. The measurement results show a power consumption of 4.3 mW. The phase noise is −91 dBc/Hz and −115 dBc/Hz at 100 KHz and 1 MHz offset from the carrier frequency, respectively.
