请教题目

小妹想请教高人几道题目

 

  Statement i): The small signal output resistance of a MOS transistor decreases with increasing bias current.

Statement ii): An Operating Point analysis (OP) is not requirement to determine the small signal AC gain of a circuit.

Which of the following is correct?

²  Statement i) is true; Statement ii) is true.

²  Statement i) is true; Statement ii) is false.

²  Statement i) is false; Statement ii) is true.

²  Statement i) is false; Statement ii) is false.

  Statement (i) the output resistance of an ideal current source is expected to be very small (almost zero).
Statement (ii) An N-input CMOS encompasses N+2 transistors.
Which of the following is correct?

         ²  Statement (i) is true & Statement (ii) is true

²  Statement (i) is true & Statement (ii) is false

²  Statement (i) is fasle& Statement (ii) is true

  ²  Statement (i) is false & Statement (ii) is false

  Which is the physical state of a MOS transistor which is switched on?

²  Accumulation

²  Strong inversion

²  Cut-off

多谢大家

 

都是模拟电路的东东，不是很熟悉了。

呵呵
MM很少的，一定要帮忙啊
