Pavs.rms=(Vs.rms^2)/4*Zs and Pavs.rms=(Vs.peak^2)/8*Zs so is Vs peak value or RMS value in the lecture? It seems to me it should be peak value and this results in my confusing about words "the factor of 4 instead of 8 is used since we are now dealing with complex power".
Again there is an Eq...
It is easeir to understand this at low freq.
Circuits may exibit more noise current or more noise voltage. Thus input noise depends on the resistance of the source. For low source resistance the noise current will have little effect but noise voltage will be dominant. For high source resistance...
Hello!
I am reading Niknejad's lecture and wonder of p.15, why "the factor of 4 instead of 8 is used since we are now dealing with complex power"?
May be the factor 2 should be because of RMS value used in equation for Pin (V1 and I1 are RMS) and actually Pavs=Vs.rms^2/(4*Zo)?
Tnx for reply!
Hi!
How to measure phase noise of a static frequency divider if I have E5052B but don't have a generator with pn better than -120 dBc/Hz ?
Could somebody suggest a paper or book to know how to do that..
Thanks for help!
Re: XVCO from LC VCO
Thanks for reply,
Let say I need +/-100 ppm variation of the frequency and the freq=400 MHz. Can I use the above circuit just replacing L by crystal ? Does temp stability degrade in this circuit dramaticcaly?
You can place a lossy transmission line model before s2p element in ADS (with the result of manufacturer meaurements data) and tune parameters of the transmission line model to get the same result as yuor lab data. It seems like the data of manufacturer are deembeded and your data are not.
