Analog Design Engineer Interview Questions
1,258 analog design engineer interview questions shared by candidates
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.
Basic RC circuits
1.They gave a RC circuit and asked me to find output voltage with given input voltage.
time domain analysis for different circuits?
1. RC ckt 2. MOSFETS input resistance. 3. Opamp positive feedback.
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)
Transfer function of a current sensor.
Given an integrator circuit with current source input, find the output as a function of time.
