Texas Instruments

A circuit was drawn on the whiteboard consisting of two op-amps with reference voltages and and input voltage going into both op-amps. The outputs of the mosfet each had diodes, which were both attached to the gate of an n-channel mosfet, which had the source attached to ground, and the drain attached to a resistor which was connected to a reference voltage. I was then asked if I knew what the circuit did.

1 Answers

I was not familiar with the circuit, and did not know it's output/operation at first glance. However, I told the interviewers that I could walk them through how I would go about solving the circuit and figuring out what the output would be. I choose two different input voltages and analyzed the circuit and resulting output for each case. My analysis and output was correct for each case, and they told me the circuit was an op-amp window comparator circuit (a simple google search will show you the basic circuit that I described above).
