Operational Amplifiers topics include: Ideal operational amplifiers, inverting and non-inverting configuration, differentiators and differential amplifiers, operational amplifiers, finite open loop gain effect, circuit performance bandwidth and large signal operations. An operational amplifier (op-amp) is a high-gain electronic voltage amplifier that has a differential input and a single-ended output. It produces an output voltage by applying an open-loop gain to the difference between the voltage at the noninverting input terminal and the voltage at the inverting input terminal. Op-amps...

It produces an output voltage by applying an open-loop gain to the difference between the voltage at the noninverting input terminal and the voltage at the inverting input terminal. Op-amps are also known as instrumentation amplifiers. They are versatile and have many uses, including as a PID/PI controller in instrumentation. They are also used in high-quality imaging applications because of their high gain. An ideal op-amp has the following characteristics: No distortion No meaningful power Infinite amplification No noise Infinite input resistance Infinite frequency response Accepts signals of any voltage Infinite gain Zero output impedance Practical op-amps draw a small current from each of their inputs due to bias requirements or leakage. Here are some other types of op-amps: Inverting amplifier: The output voltage is expressed as a function of the input current. Summing amplifier: An op-amp configured in a specific manner.
