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-Ω 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-μm CMOS receiver AFE occupies 0.04-mm2 and consumes only 4.8-mW from a 1-V supply.
