1)Introduce yourself 2)They ask questions about your projects mentioned in your resume 3)rc circuit questions(voltage vs t graphs, current vs t graphs) 4)op amp integrator and output voltage graphs and capacitor voltage graphs 5)mosfets configuration like common source common drain and common gate
At first I was asked about my project on power electronics from my resume and I was asked to explain the working of my projects and also draw the block diagram and explain regarding the same. Next I was asked questions related to 1st order RC circuits and, I was given a basic circuit of R and C and then asked to draw the output waveform of Voltage across Capacitor. Then the complexity of the circuit was increased by adding Resistors and capacitors across the initial circuit and was asked to draw the output waveform of voltage when step input was given. Then an RC circuit was given and Time constant of the circuit was mentioned and also a pulse input was given and was asked to draw the circuit. Finally some basic questions on Opamp feed forward and feed backward circuit analysis was asked.
Apply KVL and determine the output voltages in the circuit. (Circuits were like RL or RC circuits or modified Op-amp circuits, NMOS, and PMOS circuits)
what are your future aspects ?
Draw the folded cascode amplifier and find the gain/bandwidth given the capacitor load.
Project Oriented, basic knowledge about network analysis, Conceptual questions like diode is replaced these were asked
Asked related to RC circuits
Question on MOS devices and their symbols, biasing of NMOS and PMOS. Inverter Circuit using CMOS technology.
To explain the use of components in one circuit
In technical they asked about low pass filter and high pass filter,their characteristics. some question were asked related to my projects.
