Zero Crossing Detector (ZCD): Comparator circuit using 741 op amp

zero crossing detector(ZCD) using op amp 741 ic

Zero crossing detector(ZCD) is a voltage comparator that switches the output between +Vsat and –Vsat (Vsat: Saturation voltage almost equal to 14V) when the input crosses zero reference voltage. Then what is a comparator? In simple words comparators are basic operational amplifier circuits that compare two voltages simultaneously and switches the output according to the…
