    Thank you very much for your efforts, both Prof. Behzad Razavi and the uploader.
    I really respect those who devote time to help others and teach them without asking for something in return. Thank you very much for your time and knowledge. I wish you good fortune and happiness.

    Its wonderful even for practicising professional IC design professionals to sit in and refresh learning from another perspective with such a passionate educator. Prof. Razavi does a wonderful job, probably the most direct, committed and gifted microelectronics academician I have ever seen, real energetic 'roll your sleeves up' stuff, superb 🙏

      @@subhimesto7123 I learnt microelectronics on a Masters Course in the 1990s, in England. Back in the day when the UK was a serious force in the world of microelectronics and VLSI microchip design. This major/minor is not a thing in UK university BSc or B.Eng undergrad programs like it is in US University BSEE degree programs that is until you get to the MSc or MSEE graduate program level. Most Analog IC designers or Digital IC designers will have done a standard BSc Electrical/Electronics & Computing undergraduate degree. Then do a specialist Masters course in IC design (RF, analog, mixed-signal or digital), or got lucky to learn on the job in the right company. I did it the hard way, I did BSc (BSEE) Physical Chemistry didn't like the industry, so I went back to school to do microelectronics at Masters level, with a massive hole of undergrad level electronics to catch up with at night school.

    Heads up for anyone doing the free carrier density example for silicon at 300K! Razavi gives you boltman's constant in Joules/kelvin, but you need to use the version scaled for eV/kelvin to get the answer he did. this comes out to k = 8.62 * 10^-5 (eV/K)

    At around @41:46 are we assuming that we are giving silicon cube some potential of about 1V? Otherwise, does it mean that even without applying any potential, that much fraction of current is always present in intrinsic silicon wafer? I got this question because we have taken bandgap energy, which is in terms of eV, which as you said is when 1V is given. Or is that much amount of energy supplied by the atmosphere?

    @DirkJMartens Рік тому +1

    The crystal is drawn as a two-dimensional grid of neatly arranged atoms with 4 valence electrons each, forming covalent bonds with 1 electron each of its 4 neighbouring atoms, giving 8 valence electrons in the outer shell. But in practice, the crystals are three-dimensional, so each atom has 6 neighbours instead of 4.
    So why do we draw them as 2-D structures? Why can we make this simplification? What would change if we did not do this simplification? How would that impact the analysis of the semiconductor devices? What would change in the formulas we derive?

      2.Electronic ckt means we more prioritize active components whereas for electric ckt we prioritize passive components
