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 ...

Transresistance instrumentation amplifier
Proceedings of the IEEE, 1978A transresistance instrumentation amplifier (dual-input transresistance amplifier) was designed, and a prototype was fabricated and tested in a gamma-ray dosimeter. The circuit, explained in this letter, is a differential amplifier which is suitable for amplification of signals from current-source transducers.

A Chopper Instrumentation Amplifier with Amplifier Slicing Technique for Offset Reduction
2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020This paper presents a chopper instrumentation amplifier design that employs a proposed amplifier slicing technique for offset reduction. In this scheme, the core amplifier is split into multiple identical slices. During operation, the offset polarity of these slices is firstly determined by employing the second-stage of the amplifier as a static ...

A CMOS readout amplifier for instrumentation applications
IEEE Journal of Solid-State Circuits, 1991An integrated readout amplifier for instrumentation applications in smart sensor systems is presented. A fully integrated CMOS version of such an amplifier has been developed using switched-capacitor techniques. The amplifier system provides differential input capability, programmable amplification, clock generation, and low-pass filtering on the chip.

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

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 ...

An improved current mode instrumentation amplifier
Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002A current mode instrumentation amplifier in CMOS technology, is presented. The circuit is based on the use of two second generation positive current conveyors and a current differential output stage. The device exhibits high common-mode rejection ratio which is gain unaffected in a wide frequency band.
