in one of my design i need to stretch narrow
10 ns pulses coming from photo diode after
TIA stage, if i have to measure the pulse amplitude i have to stretch it at least by a factor of 100, in this search i have found a approach in which the circuit was using a capacitor after its feedback path, but i have not understood how exactly the circuit works, but when i tried to replicate it, no pulse stretch was happening, here below is the circuit and kindly suggest few modifications to the circuit or suggest an approach for the analog pulse stretch
pulse output is just zero !
EDIT1: primarily i forgot to mention that my 10ns pulses will repeat at a rate of 1Hz-50Khz, so just after some small modifications, i came with below circuit where i increased the gain and obtained pretty decent results, kindly provide your valuable comments
