We propose the wireless body-coupled power (BCP) transfer ICs with concurrent body-coupled communication (BCC) via a single electrode. Base Station (BS) IC employs the adaptive Self-Interference Cancellation for >40dB signal suppression and a Charge Replenishing HV driver for 31% power saving. Sensor Node (SN) IC adopts ground-domain separation with 89.1% cross-ground-domain power efficiency. The ICs in 40nm standard CMOS deliver power with concurrent data uplink and downlink to the entire body area.
