Hi All,
I need to stretch out a 5V roughly 1uS pulse from a photodiode to about 200uS so that subsequent circuitry can detect it. The shape of the stretched pulse doesn't matter as long as the 'stretching' circuitry can respond quickly to the photodiode input and then let the voltage decay over a 200uS time interval. One way I thought of doing this was to have the photodiode as input to a diode, the output of which goes to a capacitor and resistor in series. The capacitor is grounded and the 200uS output pulse is read from the output of the resistor. Would this work?
Thanks.
