Abstract

In this letter, a low-power non-coherent BPSK demodulator which is applicable to implantable biomedical devices is described. The proposed demodulator adopts the dual band filtering for recovering the timing and data in non-coherent way. The circuit has been fabricated with a 0.18µm CMOS technology and the power consumption of the proposed demodulator is measured at 82µW with a 2MHz carrier frequency achieving 1Mbps data rate.
