一款全集成宽带FM收发器,适用于低数据速率自主无线传感系统。
90nm RF-CMOS, 1V, 100 kb/s, 6 nJ/bit
FM-UWB收发器低数据速率自主系统片上校准
▸创新点1:全片上校准技术采用SAR-FLL控制5个DAC(3个I-DAC和2个C-DAC),在2ms内完成Tx/Rx路径的快速校准,显著提升系统稳定性和频率精度,适用于3-5GHz宽频带操作。
▸创新点2:数字可编程匹配网络通过独立调谐PA输出和LNA输入,实现Tx/Rx在3-5GHz频段的高效阻抗匹配,优化功率传输和接收灵敏度(Rx灵敏度达-80.5dBm@10 BER)。
▸创新点3:发射路径集成子载波VCO、3相CCO和三倍频PA,生成10.1dBm-pk的双FM宽带输出(FCC合规),突破传统窄带架构限制,支持100kb/s连续工作。
▸创新点4:系统级创新通过联合优化Tx/Rx能耗(Tx 630µW/Rx 580µW@1V)和6nJ/bit能效,实现低数据率自主传感应用的超低功耗解决方案,90nm RF-CMOS工艺集成度达0.9mm²。
Abstract
A frequency-agile FM-UWB transceiver (Tx/Rx) with
full on-chip calibration aimed at low data rate autonomous wireless
sensing applications is described. The subcarrier VCO, 3-phase
CCO, and frequency-tripling PA in the transmit path produce a
wideband, double-FM output at
10.1 dBm-pk (FCC compl iant).
A tunable LNA, envelope detector , limiter, and FSK demodulator
comprise the receiver. Digitally programmable matching networks
at the PA output and LNA input facilitate independe nt tuning of
Tx a
