I have a problem. I need to design a pulse generator circuit with on time of 100nanoseconds n duty cycle of 1%. The amplitude of this pulse must be 3.3V. Can i get any help on that please?
**broken link removed** might be worth looking into. The abstract says the circuit, as shown, can do 20 Hz-13 kHz, but can be adjusted by tweaking C1. I'd probably mock it up in SPICE to see how the performance is at a 100 kHz rep rate.
From initial inspection, it looks like most PWM circuits out there... a triangle-wave generator and a comparator.
Thank you very very much for all your help! im still not sure about the design n am working towards it. if there are any troubles i will get back for further assistance.
This means that you want to get an 1 (one) nanosec width output pulse ?
My humble opinion, it's almost impossible to realize it as a DIY circuit. Sorry ....
Of course it's possible to generate a 100 nanoSec pulse with 10 microSec periodic time .. : - )
Yes, the 555 is too slow to do this.
As FvM wrote above, use two monoflops.
The HC123 is a dual monoflop, working at 2...6 v, min. output pulse width < 100 nS ... **broken link removed**
i am hoping the circuit enjunear has posted will work.
Trying to get the max4232 ic now. Most dealers don't have stock.
I dont have the pspice s/w. If i could get help simulating it then, it would help me purchase the right values of resistors and capacitors.
