Abstract
In this article, a power and area efficient front-end
(FE) IC for biomedical instrumentation is presented. In addition
to ExG recording, the proposed system provides a noninvasive
arterial pulse waveform (APW) detection through direct skin
contact with a packaged silicone-coated resistive-bridge pres-
sure sensor. An automatic calibration technique is proposed to
compensate for the resistive-bridge offset and reduce it down to
1 mV . High linearity in the FE is provided through the use of
an inst
