Hi All,
I am trying to build a circuit that will do the following;
1) Take as input a gaussian shaped waveform, which is a the output of a photodiode that has been hit by a pulsed laser
2) Convert this input to a square wave output, the amplitude of which is proportional to the area under the incoming peak (i.e. integration)
I have come up with the following circuit, however I am not sure if it will work. I was thinking of using an OpAmp in integration mode, and use a monostable (7422) and switch (4066) for the reset/integration. The monostable will allow me to change the integration window.
Any help would be greatly appreciated! Do you think it will work?
Cheers,
