ua 741 square wave generator

Posted on Feb 7, 2014

A square wave generator with IC UA741 range shown here. The circuit uses positive feedback to the Schmitt trigger action and negative feedback to measure the time of the waveform. Let us assume that the output is high and the capacitor C1 is fully discharged. C1 now begins to charge through R2 and C1 R1. When tension rises above the junction of R3 an

d R4, the output changes rapidly totally negative voltage. C1 Now begins the unloading and reloading in the direction. Again contrast, when the negative voltage across C1 falls below that at pin 3, the circuit is returned quickly to totally positive repetitions value. The output endless cycle.
