Greetings everyone!
I was using a comparator as a threshold detector for part of my
circuit. Then, I realized that without any sort of feedback, the
output will most always be close to the VCC supply levels. I'm trying
to envision a threshold amplifier circuit, but my head is clouded.
Pretty much I need something that will output zero if an input signal
does not meet the threshold level and output a replica of the input
signal with no gain if it surpasses the threshold level. I am trying
to come up with this circuit using only the following components:
opamps, comparator, resistors, capacitors, etc.
Any tips to get me started?
Thanks!
