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