Hi everyone,
I want to design a variable bias supply for APD. As APDs require very high bias volatge so my target is to design a step-up converter that can take 5-12V input and deliver tunable 100-200V output. Any suggestions?
Thanks a lot.
Hi there,
I am looking forward to make a single photon counter using avalanche photodiodes. I haven't worked before with APDs before, so I am having some difficulty designing its bias, queching and preamplifier circuit. Has anyone worked with APD pls reply to me, I will give me some...
No. Can you please provide me some information about it.
The time period of one input pulse is about 1us. The shape or time period can change so circuit should handle this and differentiate every event distinctively.
The input signal's magnitude is variable and also I have to cater for the noise so I can not use simple thresholding. Also, output wave should be very narrow. As input frequency is in MHz so output pulse should be less than 1us (preferably in ns).
Input signal varies from 0 to 5 volts. Output...
Hi,
I want to design a circuit that can take positive sine waves as input and outputs spikes for individual pulses. I have attached a picture in which train of pulses below are my inputs and I want output exactly shown by above spikes.
Actually, I want to count events distinctively and each...
