I want to design a LNA using tsmc 180nm technology.Can I Apply VDD<1.8? If so,What are the disadvantages?My problem is that my dc power is high.
I'm currently working with tsmc 180nm process. I need to draw capacitor layout. Can anyone tell me how can i find the "capacitance per unit area" value.? for using poly-metal1 capacitor.
Hi all, this is my first time to post a thread here. Got a lot of help from this forum before though! I am about to design a chip with tsmc 180nm process. We have an old 180nm PDK released in 2004 which runs on IC5. A couple of days ago we got the new 180nm PDK supporting IC6, but some of my work has been done using the old (...)
I need this library for my project which is design and simulation of an analog,mixed-signal VLSI Oscillator for MEMS resonator. I went to MOSIS web, unfortunately there are some rules which I need to register under my university. I do found one tsmc 180nm technology, but that's for HSPICE not me.I really need this library and I try to
1. tsmc 180nm tech nmos transistor has a mobilty of 265cm2/v-sec where as 130nm nmos predictive tech model file shows mobility of 0.05..cm2/v-sec. such a large variation in mobility is it possible as we go down from 180 to 130nm? 2. if anybody has design procedure for simple 2 stage opamp (90nm) or any related materials pls forward it to [emai
hi friends iam using leospec for my vhdl leo spec i have one sample library scl05. i have also got another technology library from tsmc which is 180nm. i tried putting the file in modgen/data folder of leo spec. but it still is not displaying tsmc018 in the leospec tool, but when i type command related to tsmc018 library, (...)
Hi Kumarn, You will get exact number from tsmc PDK manual. see Thomas Lee took width of 437 um for 0.25 or 0.6 um process for which he has design CMOS LNA. But, your process is 0.18 um so, there must be some maximum limit which you can come to know from Design PDK manual.

Dear All, I m using tsmc 180nm Process. I'm using nmoscap pcell in layout view, when i place two same instances of same size capacitor, i m getting an error " Label short" and saying that PCELL instantiation cell "pmoscap" (unique cell name "pmoscap_PC2") from library "tsmc18rf" has the following property. L=10.84u W=10.84u. There is no (...)
is there any difference between gpdk 180nm and tsmc 180nm model parameters? Thanks in advance..
Hi all, I am designing for the tsmc 180nm. What is the maximum VDD I can use? If I make my transistor width to 250nm, can I increase my VDD? or would I have to use the tsmc 250nm process for that? Generally, if I use tsmc 180nm, but I create some of my transistors as L=250nm, then I can basically (...)
I can't comment on tsmc 180nm, but I have seen other PDKs where models had mistakes. You should troubleshoot the difference step by step, starting with series L and series R. Next, look at the shunt path (Cox, Csub Rsub). I have documented the steps here:
You can use the hspice to build your own model files for spectre if needed
That is true. For power planning, you must know your process spec. The max current per 1um. Always for tsmc 180nm is 1mA. But you need to leave margin. You can estimate power in netlist level simulation. Then , calculate the average and peak power. For power connecting, different people have different style. Some one prefer large width of power
Try at Here is the link anyways. The problem is finding the right model file for your application amongst those given above.
Hi.. how we can calculte the Cox of CMOS using the parameters of Pspice CMOS model tsmc 180nm . thanx
i am using the cadence generic process design kit, and i think it's adequate for layout and simulations. they have the 90nm PDK as well as the 180nm one. As for tsmc, i am not too sure how you can request them.

Can any one say what is an artisian tsmc library in synopsys tool?? We are having tsmc 180nm rf lib and whole package of UMC 180 Mixed mode library. but we are not having the digital library?? Is this artisian lib can be used for whole asic process even with cadence tools??? Does UMC having digital lib?? Thanking you
hello!! i m new to full custom design. i m supposed to design a 4-bit counter that should be able to operate at 3.5GHz on schematic and 2.5GHz on layout in tsmc 180nm technology. plz give me some guidelines and suggest some material to study..........
Hello friends on physical lavel any one can tell me the exact diff. between these two process.
I can give you this much from the tsmc CL018 documentation: "The information contained herein is the exclusive property of tsmc and shall not be distributed, copied, reproduced, or disclosed in whole or in part without prior written permission of tsmc."
i want to simulate a circuit in hspice with tsmc 180nm process. in this ciruit there is a vertical substrate PNP transistor. how i can present this transistor in netlist of hspice? tnx
Hi, in CMOS processes like tsmc 180nm often the minimum channel length of mVth and native Vth transistors is much larger than for normal NMOS or PMOS transistors. I need a native Vth NMOS with good RF performance, i.e. low Cgs and L. Is that possible, it would hurt the DRC and would have large leakage current (no problem in our case), but wha
What are the values of K = uCox for both nmos and pmos in 180nm ? Thanks. Find U0 and TOX here in the MOSIS WAFER ACCEPTANCE TESTS. u=U0 ; Cox(180nm) = ε0*εr(SiO2)/TOX = (8.854e-12 F/m * 3.9) / 4.1e-09 m = 8.42e
Hi everybody I want to know what does the rf suffix at tsmc 180nm library mean (tsmc18rf)? thanks
Well... in linear region you get: rds ≈ L/(W*k'*(Vgs-Vth)) so you can estimate how much area is it going to take for a certain resistive value (kn ≈ 172.5 uA/V^2; kp ≈ 35.5 uA/V^2 for tsmc 0.18 which I don't know if this is your process) Just remember that this only holds if Vds << Vgs-Vth so you have to guarantee that this
I've deisgned a LNA with two 10nH inductors(tsmc 180nm).what do you think about area of chip and it would be practical with these inductors?what's the maximum value of inductor in tsmc 180nm?how about the disadvantages of big inductors for lna?what is the value range of inductor in tsmc (...)

I need to Synthesize with RTL compiler too. I know that I need to create a wrapper for the IO pins but how to use PDO02CDG_33??? P.D. fo
Hi, I was succesful in implementing my research usign tsmc 180nm technology with mentor graphics tools, and I'm trying to work on 45nm PTM technology but kind of stuck with how to start. I would really appreciate if anyone can help me with this. -Ravi Tej
Hi all I am designing LDO using tsmc 180nm, VDD=1.8v, Vout=1.6v (200mV drop out). I have trouble running load transient response. If I connect output to a voltage source to generate load current (see attached file) the output transient very good. If I connect output to current source the spike up and down are quite huge (~400mV). Could any
In that case, tsmc is where you'd get a tsmc PDK. You can expect that it will require establishing some sort of business relationship and agreeing to stiff nondisclosure requirements, which is why you don't find it lying around loose on the INterWebzes.
E.g. this one from tsmc, publicly available via MOSIS?

I cannot make sure the improvement from 0.25 to 0.18. but i have tried 0.13 to 90nm, at least 50% improvement. 0.13 ---> tsmc 90ns -----> Fujisu Hi, heartfree What type is your design? What is your 50% improvement in the design? Frequnce, power, and what?? Thanks
Hi, Try it in tsmc website in tsmconline.I think you need to register for that.Try it once. regards, Pramod
When you synthesized your netlist, did u target the design to an ASIC technology library such as tsmc 90nm or 180nm? Could you also post the exact error message you receive from SoC? Generally, after synthesis using BuildGates or PKS, we write the new netlist as a Verilog file. This netlist is imported into SoC by specifying the std cell libra
generic 180nm process of tsmc is double well process that's mean there is no vertical pnp., L-pnp is the parasitic pnp at all. so the beta is not larger than vpnp. also l-pnp the collection is p-substrate. Base is nwell. no npn provide at all. because there is no isolated pwell unless use tri-well process. BTW i don't think beta have effect
