Operational Amplifier: Non-Inverting Op-Amp and Op-Amp as Buffer

In this article, let’s understand the non-inverting op-amp configuration , and let’s see, how it can be used as a buffer. Fig. 1 shows the non-inverting configuration of the op-amp. In this configuration, the input is applied at the non-inverting terminal of the op-amp. Fig. 1 Non-Inverting op-amp Configuration In this configuration, there is a … Read moreOperational Amplifier: Non-Inverting Op-Amp and Op-Amp as Buffer

Inverting Op-Amp and the Concept of Virtual Ground

Inverting Op-Amp Configuration: As discussed in the previous article, the op-amp is a very high gain differential amplifier. In the open-loop configuration, the typical gain of the op-amp is 105 to 106  Fig. Operational Amplifier Because of high open-loop gain, even for a small differential input between the two terminals, the output of the op-amp will … Read moreInverting Op-Amp and the Concept of Virtual Ground

Operational Amplifier (Op-Amp) Explained

What is the Operational Amplifier? As its name suggests, the Operational Amplifier is one type of amplifier. The basic function of any amplifier is to amplify the input signal. But apart from amplifying the signal, it is also possible to perform different arithmetic operations using op-amp. In the early days, when digital computers were not … Read moreOperational Amplifier (Op-Amp) Explained
