摘要：

A novel non-coherent binary phase shift keying (BPSK) demodulator featuring ultra-low power and high data rate is presented for inductively powered biomedical implants. The circuit is designed in the 0.18 mu m standard CMOS technology. Simulation results show that at a data transmission rate of 16 Mbps, the power consumption of the circuit is as low as 6.3 mu W and 1.96 mu W at a supply voltage of 1.8V and 1 V, respectively. The proposed demodulator tolerates a relatively large frequency shift for the input signal and operates properly in all process corners.
