Electrical – Small Slope On Square Wave Generator Output


I have made a square wave generator using 555, however there is a small slope on the high level of the square wave as you can see below. How can i overcome and obtain a straight high level of signal? My aim was getting 16 kHz frequency and %50 duty cycle and measurement is so close to this values. My only problem is that small slope. Thank you so much.

This is my circuit;

  1. Try adding a second capacitor between VCC and GND to further stabilize the supply, 100µF should do
  2. Add a low-pass filter to the output thats not deforming your signal too much but filters out that annoying peak. 100nF and ~50Ohms should do the trick and not deform your signal too much. If it rounds your squarewaves corners too much you can try to use a smaller cap (22nF) or smaller resistor.
