-/+-0.1V Differential Amplifier Circuit using Zero Threshold EPAD MOSFETs - This
circuit presents a differential amplifier using Zero Threshold EPAD MOSFETs that
oooooperates on 1/- 0.1v supplies. The schematic diagram is for a single amplifier
stage…Circuit Ideas for Designers Application Notes Advanced Linear Devices, Inc.

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).....(design idea added 10/05)
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.....(design idea added 6/06)

Rational Approach
AN-584: Using the AD813X Differential Amplifier - AN-584 Analog Devices
Application Notes (app note added 2/06) The AD813x differs from conventional op amps
by external presence of an additional input and output. The additional input, VOGM,
controls output common mode voltage.
AN-589: Ways to Optimize the Performance of a Difference Amplifier - AN-589 Analog
Devices Application Notes (app note added 2/06) This Application Note presents
several ways to build and optimize performance of a discrete difference amplifier. It
also recommends amplifiers that will make overall solution cost/performance
competitive with monolithic instrument amplifiers.
