About Circuit: The circuit is a simple voltage amplifier of photo diode current drop
before going to the circuit please find the attachments, which are the screen shots of oscilloscope that i am using
the circuit has a photo diode equivalent which in fact has lower current generated, which is causing the output on oscilloscope to look fluctuating its axis at regular intervals
kindly provide me a solution why the oscilloscope is behaving like this in low currnent scenario
in the screen shot attached just by putting a parallel resistance has effected the output and why ??
