Analog VLSI Interview Questions PDF

This PDF is a real interview question bank collected from my seniors’ actual interview experiences at top product-based semiconductor companies.

It contains 400+ questions that were directly asked in interviews for Analog IC, Mixed-Signal, and VLSI roles.

No lengthy derivations—just the exact kind of intuition-first, question-driven problems interviewers test you on.

Topics Covered (400+ Questions):

• RC / RLC Circuits: poles, zeros, time/frequency response
• MOS Amplifiers (CS/CD/CG): gain, resistance, inverter-as-amp
• Differential Pairs & 5T OTA: ICMR, swing, offsets, slew rate
• Two-Stage Op-Amps: UGB, pole splitting, phase margin
• Op-Amp Applications: feedback, Schmitt trigger, rectifiers
• Current Mirrors: cascodes, mismatch, gain boosting
• Noise: RMS noise, OTA noise, TIA noise intuition
• Switched-Cap Circuits: charge sharing, equivalent resistance
• Bandgap Reference: temp dependence, stability, op-amp role

Why this PDF?

✔ Based on real questions asked to seniors in interviews

✔ Covers all core analog VLSI topics interviewers love to test

✔ Compact and practical — perfect for quick prep before interviews

Format: PDF (printable, handy for revision)
