Opamp as Differentiator (active differentiator)

A differentiator opamp is an opamp configuration that produces a differentiated version of the signal applied to its input terminal. This process is exactly the opposite of integration. by interchanging the positions of components in an integrator circuit we can get a differentiator circuit. Here we’re going to discuss two types of differentiator circuit: Ideal […]

OP AMP integrator Circuit

The circuit in which output voltage waveform is an integration of the input signal is called as an integrator or op-amp integrator or integrating amplifier. The output voltage is proportional to the amplitude and duration of the input signal. Ideal op amp Integrator Circuit: The above circuit is obtained by replacing the feedback resistor RF […]

Voltage Follower OPAMP or buffer Amplifier

OPAMP buffer or voltage follower is an opamp configuration whose gain is equal unity. Voltage follower is also known as unity gain amplifier, voltage buffer, opamp buffer, or an isolation amplifier. It is used to separate two circuits having the same voltage level but different impedance. In a voltage follower circuit output voltage and input […]

Non Inverting Amplifier (OPAMPs)

A non-inverting amplifier is an OPAMP circuit configuration whose output is in phase with the input signal at the non-inverting input. The input signal is applied at the non-inverting input of the opamp. A non-inverting amplifier also acts as a voltage follower circuit. The non-inverting amplifiers also have negative feedback which is used to control […]
