CDK should not be a problem
for the sake of uniformity I recommend you download and unzip the file in /home/<user>
step 1:
create the $CDK_DIR environment variable in your .bashrc pointing to where you unzipped the CDK. The path should point to the folder that contains the bin, cdssetup...
For those who have solved the issue with verilog-a. I have a question.
I'm trying to simulate a random number generator (for a signal whose sign should be random also). The code of the block is presented below:
// VerilogA for Example, RdnGen, veriloga
`include "constants.vams"
`include...
@Prabhjot,
I believe you have ubuntu 64-bit version.
To solve your error you should install ia32-libs package. I tried with only libxext6:i386 to no avail, so ended up installing all 32-bit libraries.
Hence, from a root cshell type:
apt-get install ia32-libs

I still have my doubts whether to use average or rms function. They give different results, but literature is contradictory. Some of them use the integral of the instantaneous power divided by the period, which matches with rms at the output but average at the input. Others go directly to...
You are using 3 stages. The source follower gives you current gain.. Why don't you try then increasing the current capacity of the second stage rather than adding another one ? You can stick with you A-class output or try a B class. Also, You didn't compensate the right half plane zero. You need...
Here's the deal.
The input power comes from a solar panel. When plugged in, the initial voltage can be anything between 0 and 7V. The circuit needs a voltage above 2V to start controlling the DC converter at the input and create an ouput of 4.3 at the MPP. When plugged in though, we need to let...
Hi all,
I'm working designing a buck or boost (not buck/boost) DC/DC converter, and I have problems regarding the inrush current. The maximum tolerable is 1A but I'm achieving 2+ when powered on. How can I implement a soft start without introducing more elements in the power path ?
I've seen...
Li Ion batteries work a bit different, they have 3 possible scenarios (not even considering the temperature)
When voltage is below 3V, charge current must be low ( < 0.1C)
When 3 < Vbat < 4.2, charge current can be 1C (or even more, but it won't give you any gain)
When Vbat == 4.2, charging...
Basically, what I said is true, but I forgot some details. I assumed that the regulator device was a linear regulator in the explanation; thus, the current required from the batteries would be the same in each topology and the regulator would dissipate as much power as needed to obtain your...
Let's check some facts,
First of all, explain a little concepts:
- Parallel batteries would give you more capacity if needed. If you need 2A output and have two batteries of 1.5Ah, certainly you cannot connect them in series to provide you the current. Naturally, they will give you more...
You could use a boost converter for the 12V output and a SIMO buck converter for the remaining 3. This solution will give you the best efficiency with the less passive components, considering that you would be using just one inductor for the 3 step-down outputs. Too much noise ? too complicated...
4.2V doesn't necessarily means "fully charged". If you do constant current at 1C, you will get 4.2V but nearly 70% of charge only. When you change to constant voltage method, the voltage drop in the internal ESR of the battery lowers, and the actual battery voltage gets closer to 4.2. As it has...
Li-Ion battery model in verilog-A
Hey ppl.
Im posting here the behavioral model that I made using verilog-A on a cadence environment. Whoever is working with battery management circuits and charge/recharge simulations might find it useful.
Test it and trim it if you can, because sometimes it...
