    Characteristic
AI Thread Summary
The discussion centers on the MOS C-V characteristic, specifically the behavior of inversion electrons at different frequencies. At low frequencies, inversion electrons can respond to AC voltage, leading to CG equating to Cox. Conversely, at high frequencies, inversion electrons cannot respond, resulting in CG being expressed as Cmin, which is a function of Cox and Cs. Participants are encouraged to provide logical explanations and insights, emphasizing the need for initial problem-solving attempts before receiving assistance. The conversation highlights the importance of understanding the frequency response in MOS capacitors.

Hello, All Outstanding electrical engineering student, I have a some question.

As posted,

1. At low frequency, the inversion electrons will be able to respond to the ac voltage
=> CG (ω= 0) = Cox (Why?).

2. At high frequency, inversion electrons are not able to respond to ac voltage
=> CG (ω=∞) = Cox Cs / (Cox + CS) =Cmin (Why?)

Please.. answer logical comments. I'm so curiosity because of these matters.

Sounds like a homework problem. According to PF rules, you need to make an attempt to solve the problem before we can help. Can you tell us your thoughts on the answers?
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
