Collection Schematic

Ideal op-amps have infinite open-loop gain at all frequencies. This is a simple High Gain Wide Bandwidth Op-Amp Circuit Diagram. You can build a composite amplifier featuring high gain, wide bandwidth, and good dc accuracy by cascading the sections of a dual video amplifier and adding two appropriate phase-compen-sation components. The op amp drives a 150- load and provides a closed-loop gain of 40 dB.
