I am trying to setup a separate file server for all of our IC designs. There will be designs from 5 - 6 engineers on this server. I am looking for some suggestions into from whom I should buy the server from, OS selection, HDD considerations, backup considerations, etc. This is my first time...
I have some dummy CMOS inverters where the inputs were mistakenly left floating. My chip is now drawing too much static power. Does anyone have any ideas of how to remedy this issue without having to go in and FIB down to the metal layers and remove the physical connection? Any help would be...
I'm looking for some help or suggestions in purchasing new workstations on which we will be running mostly Cadence, but Matlab as well.
I currently use a Sun workstation running SunOS 5.8. Right now I am only running 32-b instructions, but I would like to start running 64-bit version of...
I guess what I am asking is how do find the gamma at each port? For instance, if I inject a signal at the source, what will be the gamma(s) do to the reflection at each of the other two ports?
So if I want to find the gain from one port to another, I need to know the reflection coeficients from each port, even though they are all terminated in 50Ohms? Is that what you are saying?
If I have a resitively loaded common-source amplifer and I have 3 ports (one connected to the gate, one connected to the source and one connected to the output) all terminated with 50Ohms. What would be the refection coefficient be at each port?
I would assume that they all would equal 0...
maxim adc with fft
You should use the "printvs" function in your calculator (if you are using cadence). This will create a text file that you can export to Matlab (or some other software) to run a fft. You need to run a fft because most likely (I don't know what speed you're running your ADC...
I am talking about speeds in the 1-2GHz range. I have a high frequency input signal in the 1-2GHz range and I am worried that reflections are going to kill me. Should I just up the input signal power to make sure that enough signal goes through or should I try to match the input impedance of...
For high speed analog design, I assume you need 50 Ohm matching at the input so as to ensure maximum signal power transfer. How do you achieve this without using LC matching? Do you just use a resistor or do you play with the ESD or what? Any advice would be greatly appreciated...
Re: Folding ADCs
Folding ADCs are used to get the same speed as Flash, but with less power. Although they can't achieve the same speeds as Flash, they are close. For example, at this year's ISSCC, 2 folding designs were presented, which, I believe, achieved speeds of 1.5GHz and 2GHz in 0.18um.

inductor layout question
How do you layout an inductor after importing it from ASITIC?
I was able to import it with no problems, but I am getting the error message:
"Cannot match terminal counts for inductor ipcelll cmosp18"
Does anyone know what this means or am I totaling messing up the...
