Ans Perfect balance is the characteristics of ideal OPAMP and if there is same input applied then we will get the output zero. Summing Amplifier The output voltage of a summing amplifier is proportional to the negative of the algebraic sum of its input voltages. An operational amplifier is a direct coupled high-gain electronic amplifier with a differential input to which feedback is given to control its response characteristics at its single-ended output. In most of the circuits the Op amp consist of a resistor in its feedback but in integrator we connect a capacitor in the feedback. This is one type of amplifier, and the connection of this amplifier can be done among the input as well as output and includes very-high gain.The operational amplifier differentiator circuit can be used in analog computers to perform mathematical operations such as summation, multiplication, subtraction, integration, and differentiation. Hence, the name summing amplifier. Thus to avoid this resistance Rc is added in series with capacitor C and a capacitor Cc is added in parallel with resistance R. The practical differentiator is shown below. Crimsonfury9. An integrator circuit based on opamp is shown in fig1. By introducing electrical reactance into the feedback loops of an op-amp circuit, we can cause the output to respond to changes in the input voltage over time. 3. 23. Michel van Biezen 13,427 views. Perhaps the most obvious extension is to add multiple inputs, as in an ordinary summing amplifier. This high gain makes the circuit unstable. An operational amplifier, abbreviated as op-amp, is basically a multi-stage, very high gain, direct-coupled, negative feedback amplifier that uses voltage shunt feedback to provide a stabilized voltage gain.
