How would I design an op amp with a gain of less than 1? Is this even possible? Also would it matter if I used a non inverting or an inverting op amp?
I've designed a non-inverting op amp with a gain of 2 like so. Can I modify it to have a gain of say 1/2?
1 + R1/R2

I'd appreciate some help here.
Answer
An op-amp is not required. Given the minimal requirements given, a voltage divider will do. Gain = 0.5.

If you need to buffer the output, you can just place a unity gain op-amp at the output of the voltage divider.
