Abstract

This paper presents a low-power and low-voltage analogue-to-digital (A/D) interface module for biomedical applications. This module provides an A/D conversion based on a switched-op amp second-order ΣΔ modulator, capable of interfacing with several different types electrical signals existing in the human body, only by re-programming the digital filter at the output the ΣΔ architecture employs a novel single-phase scheme technique, which improves the dynamic performance and highly reduces the clocking circuitry complexity, substrate noise and area.
