3.6-to-4.4 GHz UWB impulse transmitter and 402-to-405MHz super-regenerative receiver for medical implant devices

This paper propose a multi-standard transceiver architecture, based on 3.6-to-4.4GHz 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 L??A, mixers, IF amplifiers and ADCs. at receiver side of implant transceiver. The multi-standard external PCB loop antenna is incorporated into the transceiver as inductive element to achieve high sensitivity and selectivity. The design concept is simulated in 0.24um Ihp CMOS technology. The exchange rate upto 120kbps is achieved for detecting −95dBm signals with the power consumption of 500uW.
