A micropower low-noise monolithic instrumentation amplifier for medical purposes
IEEE Journal of Solid-State Circuits · 1987 · Vol. 22(6) · pp. 1163–1168
Abstract
A CMOS low-power low-noise monolithic instrumentation amplifier (IA) is described. The power drain is reduced by use of current feedback and by use of only single-stage operational transconductance amplifiers in the low-frequency loop. The bandwidth of the IA is designed for medical purposes (0.5-500 Hz) and it can produce variable gains of 14/20/26/40 dB, which are set by control software.
