Abstract :
A 350 muW MSK direct modulation transmitter and a 400 muW OOK super-regenerative receiver (SRR) are implemented in 90 nm CMOS technology. The transceiver tunes 24 MHz in frequency steps smaller than 2 kHz and is designed to meet the specifications of the Medical Implant Communications Service (MICS) standard in the 402-405 MHz band. The transmitter meets MICS mask specifications with data rates up to 120 kbps, and the receiver has a sensitivity better than -99 dBm with a data rate of 40 kbps or -93 dBm with a data rate of 120 kbps.
