Design of low phase noise LC VCO for UHF RFID reader


A low phase noise CMOS LC VCO (Voltage controlled oscillator) for UHF RFID (Radio Frequency Identification) reader is designed. The quadrature output differential signal is achieved through Source-Coupled-Logic frequency divider-by-two circuit. The circuit is implemented with the SMIC 0.18um MOS technology and the simulator of Cadence SpectreRF. The… (More)
