Mixed Signal Interview Questions
280 mixed signal interview questions shared by candidates
They drew a picture of the circuitry and ask me to explain how it worked, to be honest I had never seen it before, hence I answered terribly on those questions. I believe that is something only those people know, because they worked on it. If I drew my work on the board, it will stun them as well, I believe:)
Questions were from device physics, Analog Design basics like a current mirror, charge pump, LC-VCO, lumped components based circuits, Analog layout, PVT variations effects on basic analog blocks, so on, mostly from my previous work experience.
Large signal behavior of a differential amplifier
Did you analyze the noise performance of the receiver? Since your input signal is very small (400 nA), and even the noise of power supply may be larger than that, how do you suppress the noise?
Draw a FinFET NOR gate. If you were to alter the device sizes, could you directly affect the threshold voltage of the gate?
Basics analog and digital CMOS circuits
Power Storage with simple switch-cap circuit? Why using storage elements
He asked how to transform 2 by 1 MUX to a NAND gate. It was supposed to be easy, but I wasn't able to do that.
The interviews were pretty much technical. The first interviews was on projects that I worked on. In the second interview I was asked specific technical questions on ADCs, Opamp classes, buck and boost converters also question like how will I go about coding this etc.
