Abstract :
A PSK receiver uses bandpass sampling and thus avoids PLLs. It demonstrates that 2Mb/s data can be recovered with 20MHz carrier frequency in transcutaneous neural prostheses. The analog realization is able to cancel interference at 9dB larger than the signal without a filter. The demodulator is fabricated in 0.35 mum CMOS, has an active die area of 2.6 times 1.7mm2, and dissipates 6.2mW
