Non Inverting Differentiator Op Amp Circuit. This gives it dc stability an important factor in many applications. Typical digital buffer ic s available are the 74ls125 quad 3 state buffer or the more common 74ls244 octal buffer.
This circuit uses a capacitor in series with the input voltage. The voltage follower or unity gain buffer is a special and very useful type of non inverting amplifier circuit that is commonly used in electronics to isolated circuits from each other especially in high order state variable or sallen key type active filters to separate one filter stage from the other. Basic analogue op amp differentiator circuit unlike the integrator circuit the operational amplifier differentiator has a resistor in the feedback from the output to the inverting input.

This gives it dc stability an important factor in many applications. The following circuit diagram shows the non inverting integrator. Hence at non inverting terminal node we have. Let the inverting terminal of op amp is at potential v and hence non inverting terminal is also appears to be at the same potential v due to virtual ground concept.
