Ideal Op Amp Circuits The operational amplifier‚ or op amp as it is commonly called‚ is a fundamental active element of analog circuit design. It is most commonly used in amplifier and analog signal processing circuits in the frequency band from 0 to 100 kHz. High-frequency op amps are used in applications that require a bandwidth into the MHz range. The first op amps were vacuum-tube circuits which were developed for use in analog computers. Modern op amps are fabricated as integrated circuits
