I am a PhD student and here are some other questions (might be advanced) I encountered in the past interviews for PMIC and RF positions. 1. step response of LC tank. 2. start-up ckt for BGR. 3. consequence of the opamp's offset for BGR 3. latch-up (why and how to prevent it)4. how to design the 2-stage amplifier (gm) to reduce input-referred noise(and how to reduce flicker noise) 5. source degeneration (what is gm and linearity improvement) 6. 2-stage opamp: how to design input pair to reduce mismatch 7. IIP3 related questions 8. waveform of switching node voltage (Vx) of buck converter. 9. effect of ESL of output cap on output ripple. 10. opamp-based integrator (transfer function and step response)
You've selected a good set of topics. I would add Miller-compensated or single-stage folded cascode amplifiers as circuit blocks worth preparing for. Questions on how to improve PSRR, offset and stability tend to be common.
Hi, I have an interview coming up for an internship in analog design. I am doing my masters and coursework is still going on. Till what extent would you recommend I should study for the interview ?
If you are doing a project which you have mentioned in your resume then prepare that well. Focus on basics. Along with that try to prepare as many topics from video as you can, especially RC circuit, MOS basics and basic building blocks. I would give at least 2-3 hr to each topic focusing on basics. All the best 👍 and let me know how it went.

Thank you for adding your interview questions. Yes, little advance level questions but very relevant and useful.

Thanks for your feedback. Yeah I have mentioned most of these in passing in the video. And I agree these tend to be common questions in interviews.

@@analogsnippets Masters project hasn't started. I have mentioned 1-2 trainings(PD) and past Btech project(IOT). Can there be questions on this ?
