This letter presents a sub-6-GHz 100-Mb/s receiver that employs a fully balanced FSK, namely, a binary frequency-domain OOK (BFOOK) modulation. Demodulation is done based on a delay-line FM demodulator and a sideband energy detection (SB-ED) circuit with reduced noise bandwidth by leveraging a fully...
