    when calculating the SNR of adc,if i want to calculate all the noise,should the bandwidth of noise be 1/2fsample?in the book,its said that the quantization noise of adc is distributed in the range...
  2. Closed: How to decide the specification of in-band phase noise of a bluetooth PLL

    how to decide the specs of in-band phase noise of a bluetooth pll? I think the outband phase noise of a pll ,for example ,phase nosie@1MHz or @2MHz,are decided by the adjacent channel...
  3. Closed: Re: Is it right to understand the Zopt(optimized noise impedance)of ind degenarated l

    thanks a lot ,Sir.

    I got some equations of Zopt from the paper

    147693

    The value of real part of the Zopt is the first equation. A and B1 are demenstrated by the last 2 equations. Cgs is the...
