Hello All,
I have some general question about designing some Analog block and steps.
Lets consider we want to design simple Current Source biased by simple PMOS current source with given GAIN, GBW, CL
1. First should be from given GBW and load capacitance obtain the Gm
2. Then we from given...
Hello all,
I'm novice in Analog circuit design, and I have one (could be a stupid question)
So how to choose correct W/L ratio when design circuit?
At example if the calculation says that we need ratio of W/L=2, how to take a decision for the ratio. Should it be, 4u/2u or 8u/4u and etc.?
Thx
Hello,
I have an issue, trying to convert an S-transfer function to Z-domain. What the problem is:
I'm using c2d Matlab function. When conversion is done i type "step" in command window to both transfer function and results are identical.
But if I go to Simulink and draw both transfer function...
Hello,
I have a question about transfer function implementation.
So let suppose that we have designed some feedback system, which has been designed into S-domain. What are steps after, if we want to design a circuit based on this system function that we already have.
Best regards

So what is my idea. When simulation is run, and you have asynchronous process, veri often is happen that some setup or hold violation occurs. When it is happened, normally the Flip-Flop's goes to "X" state. And if "X" is propagated sometimes cause undesired circuit behavior.
So the...

Hello,
I have one question. How you simulate at example two asynchronous process, and how you avoid "X" propagation when metastability problem occurs?
Thank you for your answers.

Re: SoC design
Hello,
here is some basic point to folow
My advice is to start with basic function!
1. Firts - what this system must do.
2. Second - If you gonna to do some signal processing, type your algorithms
3. Make some block diagram of working algorithm
4. Retype your algrithms on CPU...
Re: DSP and Real signal
Yes, soryy..
So the question is:
The FFT is correct for N*period of the input signals. What is the prosedure to get exactly a N*period of input signal, to make FFT.
Hello,
I have a question about FFT of real signal.
If we have real signal, with unknown frequency, let suppouse the signal is in range in 20Hz to 20 KHz, and we must do FFT, but our FFT is limited to 1024 points of example.
What is the trick of DSP in such signal.
Best regrds

Here is verilog file with ClockMux implemented.
