S to Z domains transfer functions, Aliasing (4 Khz sampled with 5 Khz signal), how to substitute a resistor with a switch capacitor ckt, sigma delata ADC basics.
design of operational amplifier and an inverter
Questions based on academic projects
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?"
They care more about ADC knowledge. Although the job title is RF design, the manager asked many ADC and mixed signal questions.
Basic rc circuits, bandgap reference, project related questions
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 ?
