Pulse/Signal Delay circuit - Flip-Flop
« on: October 07, 2014, 08:48:55 pm »
Let me explain this:

I have one input pin on a circuit which can detect 2 things: A rapidly rising OR a rapidly falling Voltage - in short a Pulse.

Rising Pulse will switch something on and a falling Pulse will switch something off.


Sometimes a falling Pulse is generated directly after the rising voltage pulse, which would turn the circuit on and off emidiately in matter of nanosecounds. (Depending on the Transistors speed of course)


The circuit is just a Flip-Flop which needs to turn on, if I apply a quickly rising voltage through a capacitor to the Base of Transistor 1. If the Voltage is high and a Pulse with falling voltage gets through, the Flip-Flop inverts.

However I want to slow the Flip-Flop down, to just accept a pulse every 100-150ns, but I don't want any delay on the output. The only difference to a discrete Flip-Flop is, that I added a Cap to the base of Transistor 2 to basically eliminate the saturation, just to get a much faster Flip-Flop.

Well, how do I realise that? I got absolutely no Idea.





EDIT:
Oh, not neccesary anymore - found out another way. saves me some components.
