Design of a 0.6-V, 429-MHz FSK Transceiver Using Q-Enhanced and Direct Power Transfer Techniques in 90-nm CMOS

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 <inline-formula> <tex-math notation="LaTeX">$\mu \text{W}$ </tex-math></inline-formula>. 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 <inline-formula> <tex-math notation="LaTeX">$\mu \text{W}$ </tex-math></inline-formula>, 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.
