Hi All,
Using a comparator at the output of a ~30kHz sine wave oscillator to detect a level crossing.
My question is simple: will I gain or lose anything by including resistor R2?
I'm thinking it would null out effects from variation in input bias current with temperature, but am I missing something more crucial? I have tried in on my breadboard circuit, not much happened, unsure whether to include it on PCB design or not.
