This interview was for a Pre-silicon signal validation intern position. It consisted only of a phone interview, likely because I was in a different state. The interview lasted about 45 minutes and included only technical questions, with no behavioral ones.

The manager began by describing the position, his team's work, and the intern roles. He then asked me questions about my resume and the projects I had worked on.

I did not answer every question; I was unsure about a few related to oscillators. However, the manager seemed pleased with my performance overall. He confirmed right away that I got the internship, but it took about a month to receive official confirmation from HR.

What do you expect to see at the output when you connect 8 more inverters to an inverter?

Quite a few questions about oscillators and counters with different scenarios.

Why do you need to calculate gain and phase?

What is unity gain frequency?

How do you observe a ripple on oscilloscopes?
