LASER QUAD DETECTOR

Question asked by naik.chirag@conshape.com on Dec 12, 2017

Dear Sir  For one of our application we would like to implement the signal conditioning for 4 quadrant Si PIN Laser detector.  The output of the detector is current pulses with the 20nSec pulse width which we are giving to TIA for voltage conversion.  Since the o/p of detector is in nSec ,   a) Do you think Pulse stretching is a good option so that low-speed ADC can be used.  b) Do we have a signal conditioning block in a signal IC which can be use for such high precision, low noise, high BW appn.  Request you to advise
