Abstract :
This paper describes a low-power non-coherent BPSK demodulator for implantable biomedical devices. The proposed demodulator adopts the dual band filtering technique and a digital deglitching circuit for recovering the timing and data. The circuit has been fabricated with a 0.18μm CMOS technology and power consumption of the proposed demodulator is 82μW with a 2MHz carrier frequency achieving 1Mbps data rate on the 250μA internal load.
