This paper proposes a multi-standard transceiver architecture, based on UWB impulse transmitter and 402-to-405MHz super-regenerative receiver for medical implant devices. This architecture eliminates the requirement of frequency synthesizer and power amplifier at transmitter side and LNA, mixers, IF amplifiers and ADCs at receiver side of implant transceiver. The test structure of transceiver has been implemented on 0.18μm CMOS technology. The UWB impulse transmitter consumes 0.3mW from 1.5V supply at the data rate of 500Kbits/s. The 402-to-405MHz super-regenerative receiver consumes 0.5mW at the data rate of 120Kbits/s and sensitivity of -95dBm.
