Abstract

This paper presents an integrated modulator for inductively coupled biomedical telemetry. The circuit implements passive phase shift keying (PPSK) modulation and is designed to work at 13.56 MHz with a single pair of coils for both data transmission and power delivery. The data link can reach data rates up to 1/16 of the carrier frequency, i.e., 847.5 kbps in this case. To our knowledge, it is the fastest data rate achieved by a single wireless link used simultaneously for power delivery and communication in implanted medical devices. The circuit was fabricated in a 0.6-μm CMOS technology, occupies a silicon area of 0.7 mm2 and dissipates about 2 mW from a 5 V power supply at full speed of operation. © 2012 IEEE.
