We have already given many posts on Op-Amp circuits. But the list of applications of Op-Amp will be keep on going. The best Op-Amp circuit which is used to convert sine waveform into rectangular ...

Abstract: This paper proposes two isolated asymmetric rectangular waveform converters for high voltage pulse voltage generation from 100 V to -2 kV in surface coating by the physical vapor deposition ...

Using modulated rectangular waves of different time periods, the circuit presented here produces ringing tones similar to those produced by a telephone. The circuit requires four astable ...
