ABSTRACT
Abstract: The actual response of the amplifier may vary with the replacement of some aged or damaged components and this method is to compensate that problem. Here we use op-amp Fixator as the design tool. The tool helps us to isolate the selected circuit component from rest of the circuit, adjust its operating point to correct the performance deviations and to modify the circuit without changing other parts of the circuit. A method to modify/correct the performance of amplifiers by properly redesign the circuit is presented in this paper.
