66 signal integrity interview questions shared by candidates
You are given two cylindrical wires with diameter R. Consider both wires have a metallic surface (ideal) and a part of the wire was cut out in the middle. The part that was cut out from wire 1 has cylindrical shape and the part that was cut out from wire 2 has square shape symmetry. Which one of the wires has bigger capacity?
What are the most important characteristics of a transmission line?
Given two slices of a cable, with two different shapes (square hollow and circled hollow). Which one has a bigger capacitance?
How to add capacitance to a pcb board?
The technical questions were relevant and do-able. They went into some other details of circuits I told them I was not familiar with and they let that part be ignored.
Define the target impedance of a power distribution network
What is the shape of a capacitor model in frequency domain?
Fairly typical question about the most difficult problem I had encountered and how I went about solving it.
