创新点4:可配置LNA与RSSI协同设计(电路创新)。通过阻抗匹配网络重构和动态偏置技术,在60%功耗降低的同时维持-80dBm接收灵敏度,RSSI提供10dB动态范围检测。
Abstract
A Low-power IEEE 802.15.6 human body communi- cation (HBC) fully compatible tr ansceiver is implemented in 130 nm CMOS process. In this work, the proposed HBC transceiver satisfying all the standard requirements has four key features for low power consumption which includes: 1) low-power analog ac- tive filters for TX spectral mask: 30% power reduction; 2) de- layed locked loop (DLL) based BPSK receiver with the S/H oper- ation for turning off unn ecessary blocks: 40% power reduction; 3) low-powe
