Week #10: (11/5-9) Differential & Instrumentation Amplifiers

Post by rjagodowski »

This week we'll finish the discussion on Op-Amps from Week #9 and then begin to investigate Differential Amplifiers and Instrumentation Amplifiers, including the lab exercise found here.

The Op-Amp Difference Amplifier.

The Instrumentation Amplifier The labsheet containing the I.A. can be found here.

These are two Excel files to help with calculations and a demonstration of Differential Amplifier operation.

This file will perform the calculations for Differential Mode, Common Mode and CMRR for the Differential Amplifier Circuit built in lab.

This file will show how the Differential Amplifier can be used to extract and amplify a low level signal out a field of noise, attenuating the noise.
