Abstract

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 (Bluetooth, analog) is too high. Secondly, the interference management is poor, leading to unacceptable performance in real-life applications. We present a solution that meets these problems and provides a workable platform for developing wireless audio headphones. The transceiver is fabricated in TSMC 0.18 μm CMOS and consumes a peak current of 10.2 mA in RX mode and 22 mA in TX mode.
