Paper Abstract

The design of a custom CMOS analog integrated circuit to process telemetry signals will be presented. The telemetry system seeks to filter and extract information from 64 channels of signals transmitted from either chronically implanted sensors or Doppler devices. Each channel is buffered and filtered before further signal transformations. The transforming circuits include individually adjustable scaling circuit for each channel and a phase shifter and summing amplifier for each pair of channels. The scaling circuit is designed to be user-programmable thus increasing the flexibility in the signal processing algorithms implemented based on this processor. The circuit is designed using 2 im CMOS technology and fabricated by MOSIS. The design approaches of the amplifier and scaler circuits will be presented. The results will be compared to the original specifications to discuss circuit performance. 1.
