The first focused on ADC-related waveform and spectrum analysis questions, while the second mainly covered circuit stability and Bode plot–related topics.

280 mixed signal interview questions shared by candidates
2 STAGE amplifier
draw the transfer function of some MOS circuits
casex or casez is better?
Clock non-idealities/timing violations, PVT, one-hot encoding, memory configurations
Describe your previous internship experience. What is an op-amp?
design of operational amplifier and an inverter
ADC/DAC: ADC selection criteria, explain them, linearity, staircase waveform
surprisely, they asked me about my digital design project. they asked me "what was the critical path of your circuit?"
Why NAND gate realization is preferred in digital design even though we can design complete circuitry using NOR gate also? Why we study sinusoidal response of a system however we know actual input to a system may be any signal? Why we need active filters even though we can design filters by using passive components only ? Why PMOS is used as Pull up network and NMOS is used as pull down network in CMOS logic implementation. Why Minority charge carriers available at the edge of depletion layer contributes in reverse current effectively and other charge carriers are ineffective?? Why slope=-1 point is considered for Noise Margin calculations in CMOS?? What is Barkhausen criteria for oscillaton Why Astable Multivibrator is called Square Wave Generator and why not Schmitt trigger ?
