Op-Amp Gain Bandwidth Product

The gain bandwidth product is one of the important parameters of the op-amp and it is often used by the designers and electronic hobbyist for selecting the op-amp for specific application. Frequency Response of the Op-Amp For the ideal op-amp, the gain is infinite and it has infinite bandwidth. But the actual op-amp has finite … Read moreOp-Amp Gain Bandwidth Product

Op-Amp as Summing Amplifier

Op-Amp can be used as a summing amplifier by applying multiple inputs either to the inverting or to the non-inverting op-amp terminals. Inverting Summing Amplifier Fig.1 Inverting Summing Amplifier As shown in Fig.1, the op-amp is used as a summing amplifier in the inverting configuration. The inputs to the op-amp (V1, V2, and V3) are … Read moreOp-Amp as Summing Amplifier

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
