Is an NMOS device symmetrical with regard to its D and S pins? [duplicate]
Can D and S be swapped? (Assuming the body is not internally connected to S.)
The structure of a MOSFET is totally symmetric. Even the LTspice simulation shows that it can be swapped.
Does this ...

How does logic 1 get passed through an NMOS pass transistor?
I'm studying pass transistors. One thing I came across in several of the books is that when an NMOS has a logic state HIGH and the input terminal (the schematic below) is also HIGH, the output ...

How temperature difference does not affect transistors in CPUs?
Recently I learned about semi-conductors and some devices.
Today I watched a video on youtube about a guy overclocking a cpu to 7.0 ghz, while cooling it with liquid nitrogen to -192 celsius degrees. ...

Deriving the NOT logic gate using PMOS logic
I recently started learning about Field Effect Transistors (FET's) and about the MOS circuit family. From my understanding NMOS is made from a p-type substrate and n-type source/drain, whereas the ...

MOSFET switching on
I have a doubt. Consider an N-MOSFET: which is the voltage that can switch on it? The voltage between Gate and? Sometimes I read "between Gate and Bulk", sometimes "between Gate and Source", sometimes ...

Why doesn't a capacitor connected to a MOSFET charge to VDD
If an nmos which has the gate and drain connected to VDD, and the source connected to a grounded capacitor, the nmos will start conducting and the capacitor will start charging as long as VDD > VTn (...

Where are the depletion PMOS transistors?
In school, I was taught about PMOS and NMOS transistors, and about enhancement- and depletion-mode transistors. Here's the short version of what I understand:
Enhancement means that the channel is ...
