Portable audio products have not yet seen a wireless headphone solution that has been widely accepted. The main reason for this is that power consumption for current solutions is too high. We present a solution the uses a sub-sampling receiver combined with Q-enhanced RF filtering and injection-locked LO generation to provide high performance with low power consumption. This paper describes in detail the transceiver architecture, frequency plan, tuning algorithms and obtained performance. The transceiver is fabricated in TSMC 0.18 μm CMOS. The analog and RF sections of the transceiver consume peak currents of 5.2 mA in RX mode and 20.3 mA in TX mode.
