Voltage controlled one shot
Voltage controlled one shot
(OP)
I'm looking for some circuit ideas to implement a voltage controlled one shot timer that would be triggered periodically. The input would be a voltage from 1-5 Vdc and a trigger to start the timer. The output would be a single pulse with a duration linearly dependent on the input voltage. After the pulse the timer would be triggered again. Any ideas?

(VCPWM). I just think it sounds good.
This could be implemented with a small micro controller.
The micro controller must have an ADC.
If I understand correctly, then this would allow you to do things such as the following
cycle || Input Level (V)|| Output Width (ms)
1 || 0.5 || 5
2 || 1.5 || 15
3 || 4.5 || 45
4 || 2.7 || 27
and on
Let me know if you need more help

The 555 timer seems to have done the trick. I used pin 5 as the voltage input to vary the pulse width.
Thanks all
