This question is somewhat relating to electronics but I think it fits better with physics.
The leccture here (slide 13) shows that the gate to body capacitance (Cgb) in linear region is 0. However, there is no explanation at all.
I tried to find the explanation from the reference book and got...
I am having a hard time understanding flat band voltage in MOS capacitor.
Please see the picture below about MOS capacitor.
Q0 is a fixed effective charge at the surface between oxide and semiconductor and it is positive here.
The voltage across the oxide caused by the fixed charge ψox =...
Thank you!
Could you explain about unrealistic phenomenon here?
Why is there a charge accumulation?
I don't see how is each side of equation 2.61 can be zero.
For the right hand side part, the total current always flows from p to n and in the left hand side the total current always flows from p...
I simulated the oscillator. If Vdd is step voltage then the oscillator oscillates but if Vdd is constant then it doesn't oscillate. Could you explain why?
Thanks for the detailed answer.
I have some problems understanding the oscillator. The first one relating to the boldfaced part above. I don't get what you meant here.
Second problem is that how can the oscillation start up? Two transistors are exactly the same, so which one will be ON first...
Thanks a lot!
I have one more question. Assume I have an ideal parallel LC and it is connected permanently with an ideal constant voltage source. Does the LC tank oscillate with a sinusoidal waveform? I am confused because it is connected with a constant voltage source?
Yes, I searched a lot but still feel confused. I am doing some integrals and really curious.
That makes sense.
Is there an direct explanation to this even philosophy?
A point has no dimension and a line, which has dimension, is made from points together. How does something without dimension create something with dimension? I can't really make any sense of it. Could you share your opinions?
Thank you, SteamKing and AlephZero.
SteamKing: I didn't express it clearly. My question is why in circuit analysis using Laplace (for example, the analysis given in the link), the author didn't consider about the existence of Laplace Transform and Inverse Laplace Transform before applying to...
Sorry for the link. I don't know why it doesn't work when I click in that link directly.
Could you go to the first result in Google below?
