摘要/Abstract：
This paper presents an energy/bandwidth efficient frequency-domain OOK (F-OOK) transceiver for short-range communications. The transmitter performs the F-OOK modulation using a PLL based high-point modulator and a constant-envelope PA for low power consumption. The receiver consists of a sliding-IF RF front end and an 8-bit dual-channel ADC. A digital signal processing is done by an off-chip FPGA to provide F-OOK demodulation with an interference robust algorithm based on sliding-window FFT and magnitude comparison methods. A 2.4GHz 5Mb/s frequency-domain OOK (F-OOK) transceiver is implemented in 65nm CMOS. The sensitivity is -84dBm at 5Mb/s. The transceiver consumes 6.1mW from a 0.8V, achieving an energy efficiency of 1.22nJ/b with the maximum bandwidth efficiency of 96%.
