transistor level question. start from I-V curve of mos and bjt, basic layout of mos and bjt. gain of a transistor. then draw a circuit and analyse it with VDD shift and Vin shift. Define transistors region of operation. Require deep understanding of circuit and analyze it quickly and right.
Fundamental Analog Questions
They started with simple RC circuits, voltag dividers and current dividers. They also asked some OPAMP questions, closed loop gain, inv amp, non-inv amp, adder and so on. The last couple of questions were about current mirrors, and diff pairs.
