| Abstract: | This paper discusses over why the triangular wave shape distorts in operational amplifier - ca- pacitance integrating circuit and how to avoid it. We use dual operational amplifier RC feedback circuit formed by two units in one LM324 operational amplifier chip to create square and triangular wave. And the influence of circuit reactance on wave shape distortion＇s reason is mainly discussed. |

| Keywords: | wave shape distortion triangular wave operational amplifier |
