Zusammenfassung: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 \mu \text{W} . The 429-MHz FSK transmitter (TX) is also reported in this study. For eliminating circuits that consume high power, in particular power amplifier and phase-locked loop, the proposed TX adopts an oscillator that drives the antenna through an impedance matching network for power conversion. The TX consumes 390 \mu \text{W} , supplies an output power of −8.2 dBm, and achieves a global efficiency of 38.7%. The TRX was fabricated in the TSMC 90-nm CMOS process.
