If you have SPICE, HSPICE, or ELDO models in your SIL design kit, there's not too much to be changed for the LTSPICE flavor, s. these examples: 106128 106129
Hi can any body send me the model file of 0.13um technology or give me link where i can get it?u r help is greatly appreciated
In a 0.13um process are the caps MIM caps? If so, you can NOT stack them With a 1fF/(?m)? cap value I suppose it's a MOM cap. They can be stacked.
Iam designing VCO using UMC0.13um technology in cadence .Iam getting the results with pinductor from analog library.But when i replace this inductor with technology inductor simulator showing error "unable to oscillate swing at the output node is very small".can any one explain.Thanks in advance.
I am desigining some circuit which is highly dependent on the parasitic capacitance, esp. the matching of the capacitance at different location. I am wondering how reliable is the parasitic extracted cap of the cadence. Is there any special layout technique to improve the reliability? Since I am using 0.13um technology, I need to add some fi
0.13um technology and technology under 0.13um have bigger percentage of leakage power. multiple Vt std library( low, normal, high Vt) are used for reducing leakage power . They have same area. low Vt ( fast, bigger leakage) , high Vt ( slow, smaller leakage)
flxrouter4400, I am using SMIC0.13um technology. What is the simple method to slot?
We know the channel noise of MOSFET can be expressed as 4kTγgd0(γ=2/3 for long channel). When it comes to deep sub-micro technology,its value is much higher than 2/3. The question is when I simulate the LNA noise figure in spectre RF, according to the simulated results, I found γ is much closer with 2/3. I wonder how the simulat

Hi Everyone, I'm gonna design a bandgap voltage reference in 0.13um technology with 1.2V supply. can any one tell me how to start?. which topology i should choose? and if there is a numerical example it would be great. thnanks in advance, banosey
Hi, Input/output delay can be easily seen at 4 GHz. The only way to overcome that is to use minimum transistor sizes. I dont think also that there is a way to have a 50% duty cycle directly from the DFFs. My idea is to use a simple clock adjuster that ANDs the Clock with itself delayed by Δt.
A simple clock generator would be a constant current feeding into a cap and using a comparator to look at cap slope to Vref ~ compare and reset cap and repeat. This comparator then just flips a D flip flop which then generates your 50K clock. Then you make an non overlapping nand latch to make your phi1 and phi2. hope this helps Jgk
hi all i am working on a sigma delta modulator using .13um technology and i want an output from the DAC ranging from .225 to 1.575 and my Vdd=1.8 so i can't do that as my common mode input is .9 how can i do this big swing DAC

Hi, Iam doing a layout on Low Noise Ampifier in 0.13um technology using Assura Layout XL. I have encountered with DRC errors such as 1. Minimum DIFFUSION Density over 500x500 um^2 is 20% 2. Minimum PO1 density over 1000x1000 um^2 is 15%. Can anyone please give me a solution to solve these errors. And also, I want to know the reason, why d
Hi everyone, I an new here and this is my first post. I am a newbie to ASIC and as part of my semester project I am implementing a 3TDRAM. I am using 0.13um technology and Cadence Hspice and Spectre tools. I am running into some simulator issues. 1. I initially started in hspice but realised I had to do monte Carlo so i switched to Spectre. But w
I have used the ideal Gm cell and capacitor to compose a 3rd order chebychev Gm_C low pass filter.The simulation results are as follows: voltage gain=20dB, -1dB BW=10MHz,the steepness of 20MHz is 21dB. But when I design the circuits with TSMC 0.13um technology, using the same Gm and capacitor values and filter structure, voltage gain
Dear All, I need to estimate the power of my designed circuit in Synopsys power compiler(of design compiler). I have .db file(library) for TSMC 0.18um technology, but it doesn't include SRAM , and it recognize all of my SRAMS(about 3Kbit) block as DFF, which cause a lot of extra power consumption. I am looking for another

Hi, I am drawing the layout for my design using IBM 0.13um CMOS technology (virtouso). This is my first time using the IBM process so I have a few questions about the layout drawing. 1/ what is the different between pin and pad? When I insert input and output pins in my layout, the LVS can recognize them as IO Ports. 2/ Are the pads requi

Hello, I am looking for process information on CMOS 0.13um process technologies for RF and Analog Circuits. Questions like why I would use 0.13 vs. 0.18, any documentation anyone has on these processes, papers, thesis or whatever, inductors, capacitors, varactors, and so on. Thanks
25 -- > 18 -- > 13 -- > 09 --> 065 All the previous number is around 1.41 times of hte next number. Does that trigger you any thoughts?? (hints: 1.41^2 = 2)
I think it is also up to the LDO SPEC, most people like to use 0.6u~0.25um to design power management circuit.
If two identical digital core circuits, which are, implemented in 0.18um and 0.13um, respectively. What's the power consumption relation between the two implementations? Any rule of thumb or simple calculation? Thanks,
i was working on 0.18um, now i want to design the first 0.13um chip for me. i want to know what are different. thanks.
Don't worry 65nm is almost the same as 90nm and up.
Is the flicker noise corner frequency at 65nm higher than the bandwidth for most communication standards? So between 10-50MHz depending on on device size. Is the gm variability of the minimum length devices about 50%? Is the threshold voltage shift after 1year and 70°C 10-20%? Who models all these effects? Who take care of these effects
Hi all, can someone tell me the least technology used in the industry today for analog/RF design. I had heard that 0.13um is the least for analog/RF design. Is it true? has anyone done any design on analog/RF at technology lesser than 0.13um. Thanx in advance chethan

anyone worked on 0.13um tech, i read in one article that 5 metal layers are used in this tech and all r of equal thickness and resistivity. if all 5 layers r of equal resistivity whats the use? and one more which metal has higher resistance and capacitance? -- this is general Q not specific to any technology thanks in advance, Prasa
Hi, I am trying to simulate some circuits on my home PC using WinSpice. I was wondering if someone could direct me to spice models in 0.13 micron technology. There are models available for MOSFETS but no models for resistors and capacitors. I don't wish to use ideal elements. Please help
Any one can tell me there are what differences between 0.13um and 0.18um, when I run Astro. :DThanks.
standard CMOS is logic CMOS except that there are Mix-Signal CMOS tech. The diference is that: 1. MIM capacitor 2. Thick top metal 3. Deep N well 4. VTH tuned mos etc. 0.18um 0.13um 0.25um 0.35um 90nm 65ns has also to be considered.

i need cadence Ic Design 0.18um &0.13um library.if you have this files please send
90nm or .13um
Hi, you can try snake wxw = www / hzzt = h**p
becouse I do not know what cadence software engineers do. So, form cadence 99 to 2000 you should migrate de tf files(if they are parametrizable). Again, Correct my english. thx
Dear printer I think; when you use the technology files, you must use the devices and fabrication process for mas-production,so means if you use some technology file ,you must use the device for manufacturing. if you want to learn the design methodology you can use any technology file. I am not good bipolar design engineer but recently I (...)
even these universities do not provide this ! they mostly take the charts from the processing books which by turn take it from old papers & researches back to 70's & 80's. I think this will not be avaliable, as it is dependent on fab.
