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 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.
