Summing Differentiator Circuit: Summing Differentiator Circuit – Similar to the summing integrator, summing can be obtained using the basic differentiator Circuit. It can be obtained by applying more than one input to the basic differentiator Circuit as shown in the Fig. 2.50. The node B is grounded, hence potential of A is also zero. So

Ideal Active Op Amp Differentiator circuit: The circuit which produces the differentiation of the input voltage at its output is called Differentiator. The differentiator circuit which does not use any active device is called passive Differentiator. While the differentiator using an active device like op-amp is called an active Differentiator.

Summing Amplifier: As the input impedance of an op-amp is extremely large, more than one input signal can be applied to the inverting amplifier. Such circuit gives the addition of the applied signals at the output. Hence it is called Summer or adder circuit. Depending upon the sign of the output, the Summing Amplifier circuits

Non Inverting Operational Amplifier: An amplifier which amplifies the input without producing any phase shift between input and output is called Noninverting Amplifier. The basic circuit diagram of a Non Inverting Operational Amplifier is shown in the Fig. 2.20. The input is applied to the noninverting input terminal of the op-amp. Let us derive the
