Abstract

Neural prostheses have been extensively studied over the past few decades. For the applications requiring that the device be implanted into the body, all connectivities regarding the prosthetic system should be made wirelessly in order to achieve a permanent and minimally invasive implantation. Demodulator plays a key role in data integrity and overall power efficiency of the system. In this paper, an extremely efficient phase-shift keying demodulator (PSKD) family, termed quasi-coherent PSKD, is presented for the short-range wireless prosthetic systems. It has been fabricated in a 0.18-mum CMOS process and thoroughly tested. The overall design philosophy is described, and proof- of-concept results demonstrating the feasibility of the proposed design are given.
