This Design Idea offers a new instrumentation-amplifier topologythat improves ac CMR (common-moderejection). Because it uses discrete amplifiers,you can customize it for the lowestpower, price, noise, ...

And all within the same op-amp circuit, we can amplify the signal with a desired gain by choosing feedback resistor values appropriately. Another use for an op-amp is a voltage follower.

The instrumentation-amp bias current must be small, because when it flows through the large load resistor, it creates input-offset-voltage errors in some circuit configurations. Also, a rule of thumb ...

Application Notes in the Analog Engineer’s Circuit Cookbook shows step by step how to design a two-op-amp or a three-op-amp instrumentation amplifier circuit.

These days there a large number of sensors and analog circuits that are “controller friendly” meaning that their output signal is easily interfaced to the built-in Analog to Digital Convertors ...

Figure 4 shows a simple solution to the problem in an instrumentation amplifier circuit using a three amplifier configuration. The design uses a single amplifier version of the dual LTC6091, and the ...

A signal-injection circuit for control-loop analysis is flat from dc to 200 kHz, isolated from chassis ground and easily constructed with a readily available instrumentation amplifier ...

This course covers the designing and building of advanced electronic circuits and systems. The approach to design is through advanced application of sensor interfacing, instrumentation and low-noise ...
