This paper describes a dual-path noncoherent receiver architecutre with auto beam steering funciton. Two digital-assisted calibration loops are embedded in the bit slicer for robust high speed OOK demodulation. A prototype 6-8GHz dual-path receiver implemented in 65nm CMOS consumes 26.6mW at 1Gb/s with -54dBm sensitivity. The proposed receiver with high-resolution directivity not only mitigates the multipath fading effect but also adds security for smart mobile proximity communications.
