A low power high data rate wireless endoscopy transceiver is presented. Transceiver architecture, circuit topologies and design trade-offs have been considered carefully to satisfy the tight requirements of the medical endoscopy capsule: lower power consumption, high integration degree and high data rate. The prototype, implemented in 0.25@mm CMOS, integrates a super-heterodyne receiver and a super-heterodyne transmitter on a single chip together with an integrated RF local oscillator and LO buffers. The digital modulation and demodulation is also implemented in analog field and no data converters are needed for the whole endoscopy capsule. The measured sensitivity of the receiver is about -70dBm with a data rate 256kbps, and the measured output power of the transmitter could achieve -23dBm with a data rate 1Mbps. The transceiver operates from a power supply of 2.5V, while only consuming 15mW in receiver (RX) mode and 14mW in transmitter (TX) mode.
