As we know that the Operational Amplifier is a differential amplifier with two input terminals and one output terminal. The Operational Amplifier is the most commonly known analog ICs and it is capable of performing a large variety of operations that depends upon the feedback network of the Operational Amplifier for example the operational amplifier finds applications in Signal conditioning circuit, signal processing circuits, data acquisition systems and many more however all the operational amplifiers are subjected to some DC imperfections and DC offset voltage is one of them.
Let us now understand what is the offset voltage and after this we will discuss how it manifests itself in the Operational Amplifier circuits. So sit back, keep reading and enjoy learning. This post will be oriented around the DC offset voltage of the practical Operational Amplifier and the effects on the operation of the circuit due to this offset voltage.Īfter reading this post you will learn about the DC offset voltage of the Operational Amplifier, causes that leads to the DC offset voltage, effects of the DC offset voltage on the performance Operational Amplifier based circuit and also the methods for catering the effects of the offset voltage and op amp offset voltage. In my previous posts I have discussed some of the commonly known and widely used Operational Amplifier configurations. I will discuss here one of them that is the DC offset voltage of the Operational Amplifier. I have discussed in my previous posts that the practical Operational Amplifier does not exactly match the attributes of the Ideal Operational Amplifier due to which various problems arises in the operational of the practical circuit based on the Operational Amplifier. In this post I will discuss about the op amp offset voltage DC imperfections of the Operational Amplifier.
