It was a question on response of op-amp to a particular type of input. I don't remember exactly

opamp circuits( addition, substraction, multiplication, division, polynomial, etc), sinx realization( sinx approx.= x- x^3 / 6)
The structure of full bridge rectifier and relevant circuits
1. A required current to be carried was provided. A metal with current density specification was provided. Asked to calculate metal width required to carry the specified current over a particular length to meet a particular voltage drop. Follow up questions based on the above concept varying different parameters like current,length etc. 2. A basic current mirror set up. Asked about short channel effect for the devices in this set up. How the SCE impacted for these devices as current mirror ratio is changed. follow up questions on SCE. 3. Basics of source follower circuit. 4. questions regrding my course work.
Phone Interview: pretty intuional Analog Questions on mosfet, body effect, common sources etc
Analog circuit design experience
What is the resistance of CD amplifier compared with CG amplifier?
They asked about the digital filtering technique and what will be the output if a digital filter will be used for re-construction of original signal from sampled data. like difference between a digital low pass filter and a analog low pass filter
Domande relative alla struttura di circuiti standard ( opamp, bandgap, amplificatori) e ai parametri di progetto ( offset, banda, stabilità). Analisi di suddetti circuiti ed eventualmente di aspetti correlati ( parassiti, layout, ecc ecc).
I was shown an RC circuit. Basically, a first-order low pass filter. I was tasked with explaining it in my own terms.
