The picture shows the multi-stage output delay circuit. In the circuit it uses the operational amplifier as the comparator. When the operational amplifier A1's in-phase input port is added the +VE voltage, the voltage VC1 on the operational amplifier A2, A3, A4's in-phase input ports would increase by following the law of exponential curve. The operational amplifier's out-phase input port is added the voltage provided by the voltage classification divider. So each operational amplifier's input would reverse each output signal separately at the time of t1, t2, t3 during Vc1 is from zero to +VB(power voltage). That achieves the purpose of VA1, VA2, VA3's delaying progressively. It should be noted that this circuit uses dual power supplies which is positive power +VE, +VB and negative power -VB.
