Extending the bandwidth of an instrumentation amplifier

International Journal of Electronics, 1993
Abstract A new configuration for operational amplifier based instrumentation amplifier is presented. The analytical expressions are obtained and the performance of the proposed circuit is examined in relation to the conventional circuit. Simulation and experimental results are presented which establish the superiority of the proposed instrumentation ...

A chopper dc instrumental amplifier

Measurement Techniques, 1987
Because of their low zero drift chopper, dc amplifiers [I, pp. 22-23] are widely used in measuring equipment. The ratio of the maximum cut-off frequency of such an amplifier to its modulation frequency must be carefully chosen since an increase of its carrier frequency magnifies the effect of high-frequency pulse noise on the output voltage [2] in ...

A 0.01% linear instrumentation amplifier

1980 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1980
The use of combined resistive and current mode feedback in an instrumentation amplifier with 8nV/ \sqrt{Hz} input voltage noise, 2nA input bias current and 0.01% linearity will be reported. Laser trimming of silicon-chrome resistors affords 20μV input offset voltage and 0.2μV/°C drift.

Enhanced Programmable Instrumentation Amplifier

IEEE Sensors, 2005., 2006
This paper presents an instrumentation amplifier designed to calibrate sensors. As well as providing digitally programmable gain and offset, this chip offers additional features which would normally need external circuitry: low-pass filtering, output voltage clamping, input fault detection, EMI ...

A 1 V instrumentation amplifier

42nd Midwest Symposium on Circuits and Systems (Cat. No.99CH36356), 2003
This 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.

A low noise instrumentation amplifier

Journal of Physics E: Scientific Instruments, 1974
Difficulty in obtaining very low noise difference amplification with gain stability using conventional operational amplifier circuitry is considered. A design procedure eliminating the incompatibility of gain stability and low noise is discussed. The design, circuit details and performance of low noise, high input impedance amplifier with good gain ...

Servologarithmic Amplifier for Reactor Instrumentation

IRE Transactions on Nuclear Science, 1959
The instrument described is a servo which provides an output proportional to the logarithm of the input over 4 decades. Use of a special four-decade exponential feedback potentiometer makes the accuracy and repeatability much better than that obtainable with the usual logarithmic amplifiers. A period trip circuit is part of the instrument.

Dynamic Offset Cancellation in Operational Amplifiers and Instrumentation Amplifiers

2008
This paper gives an overview of techniques that achieve low-offset, low-noise, and high accuracy in CMOS operational amplifiers (OA or OpAmp) and instrumentation amplifiers (IA or InstAmp). Auto-zero and chopper techniques are used apart and in combination with each other.
