As the equation (14) in the above link , the noise In can be separated to Inu and Inc ,and Inc is correlated to Vn theoretically. My question is how to get the correlation between Inc and Vn in practice? Is it...
In the ADC datasheet , it depicts that
fIN = 169.6 MHz @ 7dBFS, 170.6 MHz @ 7dBFS
what is it meaning here?what is the...
In page 26 of the textbook it depicts that "For...
A capacitor behaves as short when initially uncharged and sudden volatage is applied and open when fully charged.
But in feedthrough,a volatge variation is in a charged coupling capacitor.
A feedthrough effect by a coupling capacitor is as below:
in which C2 is a couplng capacitor to VL2,and...
In general , amplifier has low output impedance for loading,but cascode has high.
Cascode amplifier behaves as a transconductance amplifier.
Does cascode amplifier output as a current source to drive a load?
If it does,what kind of equipment(or device) is load to cascode amplifier?
In TFT LCD displayer,black matrix is used to cover TFT and circuit elements which interfere light penetration.I know that conventional black matrix is on color filter but "integrated black matrix".
Could anyone help me understanding "integrated black matrix"?thanks.
I have read Stutzman's "antenna theory and design" about this question.In the book the explanation is that spiral antenna is self-complementary but I just don't comprehend how self-complementary does for frequency characteristic.
Pspice problem again as getting "ERROR -- Invalid outside of .SUBCKT"
The description I tested is below
.SUBCKT cc 1 2
V1 2 1 DC 1V
R1 2 1 1k
and I got...
Why did I get a PSpice error message as"Less than 2 connections at node 1"
Below is my description for a simple and easy circuit(just series of two resistor and one source),and I use PSpice Stduent.
Vin 1 0 DC
Ra 1 2 1k
Rb 2 0 1k
but it make error in PSPICE as below
I am designing a filter by HFSS and the filter has to perform as equivalent circuit layout by microwave office.......
I want to plot the result of HFSS and microwave office in one figure,but the data file from microwave office is not .s1p so it can not be plotted with result of HFSS...
I have used method mentioned from this article
"Narrow-Band Microwave Filter Design by Daniel G. Swanson, Jr"

I have a home work to write a program to simulate a wireless channel reponse..
The detial of the homework is as below:
h(t)=Σaiδ(t-τi) where i is index ,a is amplitude of Ricain distribution.
T is time delay of poisson distribution...
