A low-energy 40/160 MHz dual-band full duplex body channel communication (BCC) transceiver and a 13.56 MHz R-C oscillator-based super-regenerative transceiver are integrated in 65 nm CMOS mixed mode process for both entertainment and healthcare applications. The on-chip R-C duplexer uses notch filters for full duplex communication with 40 Mb/s data rate and combined dual-band operation shows 80 Mb/s data rate with half duplex communication. 40MHz sine wave and 160 MHz rectangular wave are adopted for modulation in the dual-band transmitter with 30 dB SNR improvement, and shared-loop BPSK receiver reduces the power consumption by 25%. The proposed super-regenerative transceiver including an OOK transmitter and an R-C oscillator-based receiver achieves >60 dB interference rejection with 100 kb/s data rate and 42.5 mu W power consumption under the 0.8 V supply.
