Composite instrumentation amplifier for biopotentials
Annals of Biomedical Engineering, 1990We present the design of an instrumentation biopotential amplifier that, (a) combines the ac coupling and high input impedance of an ac-coupled buffer with the CMRR of a simple differential amplifier or a monolithic instrumentation amplifier, (b) improves the CMRR by using a potentiometer without requiring either precision resistors or high-CMRR op ...

Instrumentation amplifiers using operational transconductance amplifiers
International Journal of Electronics, 1991Instrumentation amplifier circuits using operational transconductance amplifiers (OTAs) as active circuit elements are proposed in this paper. Two new instrumentation amplifier circuits have been described and experimentally verified, where the first circuit comprises four OTAs and five resistors and the second circuit comprises two OTAs and three ...

AC instrumentation amplifier for bioimpedance measurements
IEEE Transactions on Biomedical Engineering, 1993We analyze the input impedance and CMRR requirements for an amplifier for bioimpedance measurements when considering the capacitive components of the electrode-skin contact impedance. We describe an ac-coupled instrumentation amplifier (IA) that, in addition to fulfilling those requirements, both provides interference and noise reduction, and yields a ...

Multichannel instrument amplifier
Measurement Techniques, 1962The design of multichannel devices with a common intermediate amplifier provides a reduced measurement error and a considerable reduction in the amplifying elements, which in turn raises the reliability of the device and reduces its size and weight.

A 1 V instrumentation amplifier
42nd Midwest Symposium on Circuits and Systems (Cat. No.99CH36356), 2003This paper describes the design and the implementation of a 1 V instrumentation amplifier in a 1.2 /spl mu/m CMOS process with V/sub TN/=0.6 V and V/sub TP//spl ap/-0.8 V. The instrumentation amplifier has a peak-to-peak output signal swing of /spl plusmn/350 mV. It uses two 1 V opamps and a Norton amplifier.

Principles of Instrumentation Amplifiers
2018This chapter is dedicated to the general principles of the Instrumentation Amplifier, a particular type of differential amplifier hereafter called IA. Its basic applications are reviewed. The definitions of Common-Mode Rejection Ratio (CMRR) as the most important property of IAs are discussed. It is shown that the CMRR definition is different in single
