Could someone explain to me, how to get a pulse width, larger than 50% duty cycle, I'm using my circuit simulator, and just made a classic transistor schmitt trigger circuit, it works fine for upper and lower threshold voltages, it triggers a square wave, with a sine wave input, as the sine wave amplitude is increased. As the input sine wave is increased in amplitude, the width of the square wave pulse increases as well.
But when it gets to full input voltage on the sinewave input amplitude, then the squarewave ends up being at 50% duty cycle.
What do I need to do to be able to get past the 50% duty cycle limit?
Thanks.
