Differentiator Circuit using a 555 Timer Ic

[ajaysankarg3]

I want to make a Differentiator Circuit using a 555 Timer Ic , what were the conditions i need to maintain
i bought the 555 timer ic at
BIGBELECTRONICS

can anyone help me in this

To diferentiate a pulse you need a resistor, a capacitor (or an inductor). With or without active circuits.
But until understand you will use the 555 to compose a pulse of different time of the original. Then you need to build a monostable whose RC constant be properly chosen to the new time you want, and a much smaller RC time entering the original pulse at the trigger input, properly biased.

Can you explain what to differentiate and to what?
The 555 is a very specific yet universal timer ic.
The input is a window comparator which outputs set/reset a flipflop. So when a difference is sensed between treshhold and/or trigger at the edges of the window (1/3 & 3/2 Vdd), the output and discharge switch accordingly, but no subtle analogue value. CV is for modulating the window only (or not).

I have no direct memories (40+ electronic years) of applications as 'differentiator', other then all timer circuits in the application notes.

Yeah, is very "rare", but 'till I understand he wants to make a pulse, narrow than the original one. So I gave my idea under those conditions. Let's wait for his answer.

So, ajaysankarg3, enlighten us your challance. We're happy to contribute.

I suspect spam. Trying to promote the site linked in his one-and-only message. Not knowing that a '555 is not a prime pick for a differentiator.

If I am wrong, I apologize.

Possibly a student wanting help with a homework assignment (which he may have misunderstood)? We used to get lots of those on here, but fewer in recent times. Maybe they all go elsewhere now for illicit help?

Here's a detailed and informative 555 timer IC tutorial by Tony van Roon: groups.ist.utl.pt/lee/SUBA/Suba_files/555/A_555_Timer_IC_Tutorial.htm

Are you planning to do edge detection and put a differentiator on one of the input signals?
