title = "A low noise VCO with quadrature prescaler for UHF RFID reader",
abstract = "A low phase noise CMOS LC VCO working at 1.8GHz with quadrature prescaler for single-chip UHF 860-960MHz RFID Reader is proposed in this paper. The symmetrical filtration technology is adopted to suppress noise for complementary cross coupled LC VCO. FOM method is applied in low-noise VCO design. Injection locked prescaler with ring oscillator core can provide wide locking range. The proposed LC VCO and prescaler are implemented in IBM 0.18μm RF CMOS technology. The measurement results show that the VCO achieves a phase noise of -132dBc/Hz at 1MHz offset from 1.8GHz while drawing 10.5mA from a 3.3V power supply. The tuning range of the proposed LC VCO covers from 1.71GHz to 2.19GHz. The locking range of the proposed prescaler is 66.35\% with in-phase and quadrature outputs.",
