本文提出了一种能量高效的接收器AFE，用于通过人体作为数据传输媒介从微弱的宽带脉冲信号中恢复二进制数据。该接收机采用宽带对称触发技术，数据传输速率为10 Mb/S，输入灵敏度为-27 dBm，工作带宽约为200 MHz。片内对称偏置电路为高速对称操作提供50欧瓦的输入阻抗，从而实现低功耗。提出的运算放大器是基于低压全互补折叠共源共源共栅结构。它的直流增益为60分贝，带宽为684 MHz，功耗为1.5 mA。0.18微米的CMOS接收器AFE的面积为0.04平方毫米，1V电源的功耗仅为4.8毫瓦
This paper presents an energy-efficient receiver AFE to recover binary data from the feeble wideband pulse signals through the human body as a data transmission medium. The receiver AFE exploiting wideband symmetric triggering technique delivers data at 10-Mb/s rate with the input sensitivity of -27-dBm and the operational bandwidth of about 200-MHz. The on-chip symmetric bias circuit provides 50-Omega input impedance for high-speed symmetric operation leading to low power consumption. The proposed operational amplifier is based on the low-voltage fully complementary folded cascode topology. It exhibits 60-dB DC gain and 684-MHz GBW with 1.5-mA dissipation. The 0.18-mum CMOS receiver AFE occupies 0.04-mm2 and consumes only 4.8-mW from a 1-V supply
