Abstract

As integrated circuit technology advances, implantable biotelemetry devices will be able to handle more complex functions. Their flexibility and performance can be increased by incorporating multi-rate and multi-modulation schemes. The Class-E transmitter has been a primary choice so far in implantable devices as it provides low-power design with high-power efficiency. This paper investigates the design procedures of class-E amplifier for different modulation schemes in biotelemetry systems. A Class-E transmitter circuit that produces OOK, FSK and PSK modulated signals has been designed, optimized and analyzed in terms of a second order system for general implantable electronics.
