Hello all,
Please forgive what to many will be a simple response, but I'm a software guy and this primitive hardware stuff is new to me
I'm trying to detect a pulse which is about 100mV. Well, it rises to 100mV, then trails off quickly as the 4pF capacitor that it was generated from discharges.
I'm figuring I can use a comparator, which a Vref of about 70mV, then have it output at a level that my microcontroller can read it.
Can comparators read those sorts of voltage levels? Or do I need to run it through an amplifier first?
Many thanks.
