Impedance Measurement with the AFE4300
Van Yang, Praveen Aroul, Kevin Wen................................................................. High Performance Analog
ABSTRACT
This article gives a brief overview of bio-impedance measurements and discusses the methodology to
measure impedance with AFE4300, an analog frond end for weight and body composition measurement.
The article also includes the step-by-step procedure to calibrate and measure the impedance using the
AFE4300 demonstration kit and the PC application software. The measurement results of two typical bio-
impedance networks are analyzed.
