Abstract
A dynamic bridge system with common mode range extension includes a dynamic bridge circuit having a pair of input terminals for receiving common mode and normal signals, a pair of intermediate terminals and an output terminal and reference terminal; a differential amplifier has its inputs connected to the intermediate terminals and its output connected to the output terminal; a pair of balanced loads is each connected at one end to an intermediate terminal; and an inverting amplifier responsive to the common mode signal at the inputs of the differential amplifier drives the other ends of the balanced loads in opposition to changes in the common mode signals at the inputs of the differential amplifier.
