Abstract :
Precision operational amplifiers are used to gain low electrical signals accompanied by high level of noise. They have low offset voltage with thermal drift, high common-mode rejection ratio, high input resistance and low noise. The dual precision operational amplifier designed in this article can be used to construct devices of high accuracy with fractional error (instrument amplifiers with high gain, voltage stabilizer, precision integrators, integrators, detectors etc.)
