| 摘 要： | 结合EPC global C1 G2协议和ETSI规范要求,讨论了频率综合器噪声性能需求,并设计实现了用于单片CMOS UHF RFID阅读器中的低噪声三阶电荷泵锁相环频率综合器.在关键模块LC VCO的设计中,采用对称LC滤波器和LDO 调节器提高VCO相位噪声性能.电路采用IBM 0.18 μm CMOS RF工艺实现,测得频率综合器在中心频率频偏200 kHz和1 MHz处相位噪声分别为-109.13 dBc/Hz和-127.02 dBc/Hz. |

| Abstract: | Requirements of frequency synthesizer on phase noise were discussed based on EPC global C1G2 and ETSI multi-protocol operation.A low phase noise 3rd-order II-type charge pump phase locked loop for single-chip CMOS UHF RFID reader was presented, which acted as a frequency synthesizer.Symmetrical LC filters and LDO regulator were used to improve phase noise performance.The circuit was implemented in 0.18 μm CMOS RF technology.Test results showed that the frequency synthesizer had a phase noise of -109.13 dBc/Hz and -127.02 dBc/Hz, at 200 kHz and 1 MHz offset from the carrier, respectively. |
