Hello Adem,
I couldn't understand the relation of your question to mine. I have no compression, just the normal images.
If you are asking a question yourself, the best way is to that you rather start a new thread and being more specific about your question usually helps, what kind of...
Hello,
So I have a function that has an inverse Lorentzian shape (i.e. -L(x)) and thus it has a local minimum. Now the minimum is at zero, if there is no shift. However as I measure it, the minimum is not exactly at zero, but it is a bit off, i.e. shifted to the left or to the right. What I...
Hi,
the upsampling is not that straight forward as down sampling.
there are various methods to do the upsampling, the easiest in my opinion is linear interpolation, but you can use quadratic methods, cubic spline interpolation etc... depends on why you need it for...
so you have to specify your...
Hi emresel,
I am actually not trying to add gaussian profiled noise. These gaussians I am trying to add are my signals, like point-spread-functions I get while imaging point shaped objects.
Actually I fixed the problem with some help from somewhere else. My problem occurred while trying to use...
Hi, I am trying to create some Gaussian distributions and put them on an image. The Gaussians have randomly created parameter (amplitude, position and standard deviation). First I put the parameters into vectors or matrices, then I am using ngrid() function to get a 2d space to create the...
Hi again,
Checking further, I found this document and solved the problem.
If you encounter the same problem, this is the solution.

Hi,
I want to use a part in my simulation. The part is ADA4817-1. The Analog devices provide a file that is found in ADA4817-1 | Low Noise, 1 GHz FastFET Op Amps | FET Input Amplifiers | High Speed Op Amps (> 50 MHz) | Analog Devices under "spice models". However the file has an extension ".cir"...
chuckey, thanks for your reply.
from what you have said, I understand -10dBc is not enough. Then what should be the appropriate value of the harmonic suppression so that the oscillator can be assumed to be a pure sine wave oscillator.
Thanks again
hi Chuckey,
I checked the datasheet of this voltage controlled oscillator but could not find wether the output is a sine or a square wave.
How can I understand it?
part: CVCO33CL-0110-0150
datasheet is in specifications link in Crystek Microwave
thanks
Hi,
I am using this ADC, AD7656. It says that it operates with 250kSpS. however when I operate it with 200kHz, it does not work properly.
I am using only two channels of the adc. When I ncrease the frequency of sampling, the second channel starts to output wrong values sometimes. Although it is...
hi,
virtuoso tells you these values. just simulate and print or annotate the component parameters of the transistor you want. a lot of parameters will be listed and you can search for the related capacitances. I guess, the input capacitance of an inverter is Cnmos + Cpmos. Cnmos = Cox,n + Cgd,n...
hi,
so should I bias the transistors so that their drain currents are equal? or should I try to arrange their Vds so that they can stabilize at a value at the output?
But I don't know the aspect ratios of the transistors, should I assume a value? I can empirically determine values too, but...
But the rest is right? Because the circuit is actually designed for HV = ~110V and the 20k res is actually 56k in the upper voltage divider part.
what should be the right values? what is the logic of the biasing? Any hyperlink that I can access to get some theory of the circuit would be great...
HV Amplifier - biasing
Hi,
I have this circuit, a high voltage amplifier.
I've measured the bias voltages of the transistors and marked them on the schematic:
I have removed the connection of the drains of the fets. otherwise they pass too much current and burn, which make sense with the...
