| S Oct 3 at 13:41 | comment | converted from answer | AnalogKid | Please update the question with more information: How much current is available from the V1 signal source? What is the load impedance of whatever circuit or device this circuit output is driving? | |

| Oct 3 at 13:33 | comment | added | Marcus Müller | @Andyaka fair, yes, but if identical, then "obviously" no change at all can be made, and I don't think that was the assumption when the question was asked. | |
| Oct 3 at 12:50 | comment | added | Andy aka | @MarcusMüller the word used was identical. Quite often in engineering you have to be a true pedant. | |

| Oct 3 at 11:31 | comment | added | Marcus Müller | Arseniy, it's impossible to know whether a circuit can be simplified if it is not known what the circuit is used for. "delay circuit" doesn't tell us anything – and in fact, it's likely you want something specific, considering there's a otherwise "useless" R2 at the output of your U2. So, describe what purpose this delay circuit serves – what does get connected to its output, what is connected to its input, why is the supply voltage what it is (a bit on the low side for the deprecated NE555), etc. | |
| Oct 3 at 11:22 | comment | added | Marcus Müller | @Andyaka but compared to the delay introduced by the NE555, these should be pretty much zero. The question is whether you want the edge-sharpening that U2 brings or not, to me | |
| Oct 3 at 10:28 | comment | added | Andy aka | The gates will introduce delays so no, it can never be identical. | |
