1 Answer

Answer :

The major limitation of ordinary diode is that it cannot rectify voltages below the cut – in voltage of the diode. A circuit designed by placing a diode in the feedback loop of an op – amp is called the precision diode and it is capable of rectifying input signals of the order of millivolt.

Drawbacks of Series Diode Clippers?

Description : Drawbacks of Series Diode Clippers?

Last Answer : In series clippers, when diode is in ‘off’ position, there should be no transmission of input signal to output. But in case of high frequency signals transmission occurs through diode capacitance which is undesirable. This is the drawback of using diode as a series element in such clippers.
