![]() $$C\frac$ is having a negative sign, which indicates that there exists 180 0 phase difference between the input and the output. The nodal equation at the inverting input terminal's node is − So, the voltage at the inverting input terminal of op-amp will be zero volts. An op-amp has two inputs, inverting terminal (labeled -) and non-inverting terminal (labeled ). That means zero volts is applied to its non-inverting input terminal.Īccording to the virtual short concept, the voltage at the inverting input terminal of opamp will be equal to the voltage present at its non-inverting input terminal. In the above circuit, the non-inverting input terminal of the op-amp is connected to ground. The circuit diagram of an op-amp based differentiator is shown in the following figure − This section discusses about the op-amp based differentiator in detail.Īn op-amp based differentiator produces an output, which is equal to the differential of input voltage that is applied to its inverting terminal. DifferentiatorĪ differentiator is an electronic circuit that produces an output equal to the first derivative of its input. ![]() Please note that these also come under linear applications of op-amp. This model shows a standard inverting op-amp circuit. This chapter discusses in detail about op-amp based differentiator and integrator. The electronic circuits which perform the mathematical operations such as differentiation and integration are called as differentiator and integrator, respectively.
