Abstract

A 429-MHz ultra low-power frequency-shift keying (FSK) transceiver (TRX) that is operated at 0.6 V at 200 kb/s is presented in this work. The receiver (RX) used in this work uses a proposed frequency-to-time-based technique that demodulates the output data by discriminating the corresponding date period. The proposed RX provides a sensitivity of −85 dBm at a bit error rate of 0.1% and consumes a power of 146 µW. The 429-MHz FSK transmitter (TX) is also reported in this study. For eliminat- ing c
