The questions ranged from basic Analog concepts and like a GRE exam, the level of difficulty would be raised based on my answering capabilities. The basic concepts could be from noise sources of an Amplifier to more detailed concepts on my Master's thesis topics.
IC design questions, but not something a fresher would have learned in his college time
1. Basic questions around transistors - particularly large W/L ratio ones. 2. A couple of circuits with pmos and nmos in a current mirror configuration - I was asked what would be the node voltages as a function of input to one of the transistor's gate. 3. Layout/cross section of inverter and small signal model of MOSFET
mostly about DIGITAL ELECTRONICS and in analog electronics
2>why transistor give 180 phase shift?
why latchup occurs in mosfet
what are various modes of op amps
In a differential pair with active current mirror load, what is the output value for 0 input voltage difference? Substantiate your answer.
All about basics . Confusing here and there on topics you know to test your ability on your standards.
Variation of mos characterics with temperature.
