AC Coupling Instrumentation Amplifier Improves Rejection Range of Differential DC Input Voltage - EDN-Design Ideas:  The need for conditioning low-level ac signals in  presence of both common-mode noise and differential dc voltage prevails in many applications. In such situations, ac-coupling to instrumentation and difference amplifiers is mandatory to extract  ac signal and reject common-mode noise and differential dc voltage..

Active feedback IC Serves as current sensing instrumentation Amplifier - EDN-Design Ideas:    High-speed current sensing presents a designer with some significant challenges. Most techniques for sensing current involve measuring  differential voltage  current produces as it flows through.

Amplifier and Current Source Emulate Instrumentation Amplifier - EDN-Design Ideas:  The classic threeor two-op-amp instrumentation-amplifier circuits are standard ways to amplify a small-amplitude differential signal contaminated with high common-mode noise. In some applications,  signal source is floating with high-series-output impedance and thus requires an appropriate high-input-impedance amplifier..
