They basically asked about question related to RC and LC circuit ,op amps related questions. Questions relation to bode plot and lead lag compensator. there were also question related to CMOS circuits and seconds order equation relating network analysis
Start up circuit of a BGR ? ( from masters project)
The interviewer started with basic step response of low pass RC circuits. Then went on adding resistors and capacitors to the circuit. Then he told me to analyse an opamp circuit with step input. Then he went to bode plot of a first order transfer function. He asked why the transfer function does not blow up at a pole in the bode plot.
Which do you prefer analog or digital and which subjects have you studied?
Basics of Operational Amplifier,VLSI,RLCand Analog Integrated Circuits.
RC circuits, OPAMPS, frequency response and final year project.
What is the output of a RC filter
General 1st order and 2nd order circuits. Basics of mosfet and BJT
basic questions like output of rc circuit with step input, and opamps in different configurations. impedances of mosfets in different circuits, basic lc oscillators. your circuit designing skills and understanding basics of how FET's works.
Questions were from device physics, Analog Design basics like a current mirror, charge pump, LC-VCO, lumped components based circuits, Analog layout, PVT variations effects on basic analog blocks, so on, mostly from my previous work experience.
