Multichannel instrument amplifier

Measurement Techniques, 1962
The 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 300°C dynamic-feedback instrumentation amplifier

IEEE Journal of Solid-State Circuits, 1998
A high-temperature instrumentation amplifier that uses dynamic feedback is presented. It realizes dynamic feedback by means of a rotating chain of resistors to compensate for resistor mismatches. An 11x dynamic-feedback instrumentation amplifier has been integrated in a standard junction-isolated 1.6-μm CMOS process and realizes an average gain error ...

Instrumentation Amplifiers and Operational Floating Amplifiers

2011
With the definition of universal active devices in Chap. 1 we have seen that the operational floating amplifier (OFA) is the most universal active device, even more universal than the operational voltage amplifier (OVA), abbreviated to OA or OpAmp, because of its most wide usage. The OpAmp provides us with accurate output voltage control. Additionally,

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.
