Abstract

A transmitter (TX)/receiver (RX) pair using galvanic coupling to achieve in-body to on-body body channel communication (I2O-BCC) for ultra-low power (ULP) miniatur- ized implanted applications is presented. The I2O-BCC enables low loss communication ( <40 dB) within 10–40 MHz band and up to 10-cm in vivo communication distance using the body as a transmission medium. Injection locking (IL)-based frequency-to-amplitude (F2A) conversion demodulator is pro- posed in RX. It can handle more than 20%
