The circuit was designed for the purpose of creating a voltmeter with high impedance that would measure Direct Current voltages across any types of circuits. CA3130 – a BiMOS operational amplifier ...

Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
