35.4 A NearLink 2.0 Compliant Dual-Band RF Transceiver for Smart Wireless Personal Audio Applications

This work presents a NearLink 2.0-compliant dual-band RF transceiver. Compared with traditional BT/BLE counterparts, this design achieves receiver figures of merit (FOM) of 188.7 dB in the 2.4 GHz band and 185.2 dB in the 5 GHz band, exceeding the state-of-the-art by <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$&gt;4 \text{dB}$</tex>. Furthermore, it demonstrates a 30.9% 2.4GHz-transmitter-system power efficiency with exceptional EVM performance: 3.3% in <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$3 \text{Mb} / \mathrm{s}$</tex> BT Enhanced Data Rate mode and 3.64% in 4M-16-QAM NearLink 2.0 mode <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(16 \text{Mb} / \mathrm{s})$</tex>.
