What conditions could be expected to occur if one or both inputs of an op amp...
Question 1: Can an op amp work with both of the inputs floating? I assume that due to the input offset voltage if both the inputs are floating, the output would be +Vsat/-Vsat. Am I wrong? Question 2:...

How can I prevent reverse current in this circuit?
I learned that you can use an op amp to do differentiation. Further that you can chain them to do higher order differentiations. So I tried simulating this on LTSpice. A single differentiator circuit...

I selected some amplifiers based on their input and output voltage since the howlands Gain is Vin/R also on how much current the amplifier can supply. i selected ones that are 100mA and up, what other...

Question about feedback in a current reference
I'm studying the following Vbe-based current reference: The author of my book says: Observe that the circuit has two feedback paths around the gain stage. One positive, the other negative. Assuming...
