Hi everyone, I'm Giacomo from Bologna, Italy,
I'm trying to set up a negative peak detector for a signal that is only 5 us long, so very high frequency and a minimum of -100 mV height (the attachment can clarify the shape of the signal). I followed this thread about the negative peak detection: http://forum.allaboutcircuits.com/showthread.php?t=30770 , and I'm asking myself if the circuit proposed by Audioguru can work (adjusting properly C and R in the circuit) with such fast signals. So if it can work what are the best values for resistances and capacitors to acquire that signal? ( I'm actually using max4477 as op-amps). My final objective is to keep the peak value for about 1 ms and read it with an arduino analog input. Thank you in advance for helping me!
Giacomo.
