1.Predict the voltage waveform shape across the capacitor in a network of series and parallel resistors using engineering intuition and thought process( sorry, no pen and paper) 2. Voltage across a resistor in a circuit with OpAmp( which I later identified as the Howland Current Pump circuit) and two more questions which I don't recollect.
control system questions,were mstly ther
draw the voltage curve of rc charging circuit and why is the curve exponential.
1.RC ,RL, RLC Ciruits
Step response of RLC networks, MOS circuits, amplifiers, negative feedback, Miller compensation
1.They gave a RC circuit and asked me to find output voltage with given input voltage.
time domain analysis for different circuits?
Current through a capacitor for example.
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.
