An ASK demodulator for data telemetry in biomedical application

Abstract

This paper presents a demodulator design for Amplitude Shift Keying (ASK) based wireless telemetry system in biomedical application. It supports up to 300Kbits per second (bps) data rate and detects envelope with modulation index of 1% or more. The design includes a single-to-differential OTA, a current mode full-wave rectifier, a log-domain peak detector… (More)
