Abstract:
A 0.6-V, 200-kbps, 429-MHz ultra-low-power FSK transceiver (TRX) is presented. The receiver (RX) adopts a frequency-to-time based demodulator, which detects high or low frequency to determine data output level. The proposed RX achieves -85-dBm sensitivity at 0.1% BER and draws 0.146 mW. A 38.7% global efficiency, 429-MHz FSK transmitter (TX) is also reported in this paper. To remove the power-hungry sub-circuits, such as PA and PLL, the proposed TX is essentially constituted by an oscillator which drives the antenna via an impedance matching network for power conversion. The TX draws 0.39 mW and delivers -8.2-dBm output power. It achieves 38.7% global efficiency. The transceiver is fabricated in 90-nm CMOS process.
