Op-Amp Power Supply Rejection Ratio

What is Power Supply Rejection Ratio of Op-Amp ? Power Supply rejection Ratio (PSRR) specifies that if there is any change in the supply voltage, then how it will affect the output of the op-amp. For op-amp, if there is any change in the supply voltage, then it should not affect the output of the … Read moreOp-Amp Power Supply Rejection Ratio

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 (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
