Abstract

We present in this paper a new integrated amplitude shift-keying (ASK) demodulator dedicated to electronic implantable device (IED) systems. ASK modulation/demodulation is commonly used by IED when transmitting data witch is usually carried out using remote transmission systems. The proposed ASK demodulator is designed to process input currents with a very small modulation depth (the difference between the two allowable amplitude levels of the ASK modulated input current). The demodulator is designed with Cadence CAD tools and Specter simulator using 0.18 mum, 1.8 V CMOS technology process. Preliminary post-layout simulation results are promising and the circuit is now under fabrication process
