AC Coupling Instrumentation Amplifier Improves Rejection Range of Differential DC
Input Voltage - 09/30/04 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.....(design idea added 12/04)
Active feedback IC Serves as current sensing instrumentation Amplifier - 07/24/03
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.....(design idea added 12/04)
Amplifier and Current Source Emulate Instrumentation Amplifier - 11/13/03
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.....(design idea added 12/04)
Amplifier cancels common mode voltage - 05/10/07 EDN-Design Ideas: You can
eliminate common-mode-voltage errors with this amplifier circuit that subtracts out
the error.....(design idea added 5/07)
