Design of A CMOS closed-loop system useful for bio-impedance measurements

Abstract

This paper proposes a method for impedance measurements based on a closed-loop implementation of CMOS circuits. The proposed system has been conceived for alternate current excited systems, performing simultaneously driving and measuring functions thanks to feedback. The system delivers magnitude and phase signals independently, which can be optimized… (More)
