I need to find the SPICE level 1 parameters of a MOSFET using a simulation of a level49 (bsim3) model. I dont even know where to start. what kind of simulations do I need to create and how can I calculate the parameters? I am supernewb in electronics. Thanks in advance for your help!
The aging simulation capability doesn't depend on the simulator; it depends solely on the model, i.e. if the model (bsim3 Level 49 or 53) includes the NBTI- or HCI-relevant parameters, s. the appended hspice_simulation+analysis_user_guide.pdf . Both Synopsys' HSPICE's MOSRA (MOS
You should find from the documentation of your process the model that runs behind and from it's respective manual search for the definitions of the above terms.If the model is BSIM check this link : bsim3 Homepage - Archive FTP Stuff
ADS2008 may not recognize bsim3.3 model..Check first this Otherwise use later version like ADS2009U1..
Run DCOP sim on simple MOS schematic and plot gcc for gate and for drain-bulk I forgot how it's named - look into bsim3 model documentation.
How do I get the value of \lambda ( the channel length modulation parameter for MOSFETs), starting from a bsim3 model? and what about N_A, N_D (acceptors and donors concentrations) and the \gamma coefficient for the body effect? Is there a web reference with all of the bsim3 parameters (...)
You can calculate mobility using bsim3 or bsim4 parameters. also Cox is Eox(E=epsilon) divided with Tox (oxide thickness). You can grab a textbook using BSIM models to calculate those parameters. You can use winspice for spice simulations. I suggest v1.05.07 for simulations with bsim3. v1.06 is blocking (...)
Are there any processes that offer BSIM4 parameters?? Most of the processes I came across only offer bsim3 compatible parameters. Cadence Spectre offers BSIM4 model, but I never found the required process parameters that take advantage of BSIM4 advanced modelling.
I have a problem. If I have a transistor biased in saturation, i can get the value of current from cadence. my question is I want to verify that this current is right. Which version of BSIM model should I refer to, and from where I should get these parameters to plug into this equation. I have seen bsim3 equations and they (...)
For bsim3 model, it's not easy to do hand calc. You can do dc sweep of pmos/nmos for a few w/l cases and get lists of their parameters such as vdsat, vth, beta for future reference.
there is no such parameters in the bsim3.3. However, you can get it from the ID vs. VD curves as it defined.
Dear all, I have a question about the bsim3v3 model and Hspice: For some calculations, I need to know some parameters such as Esat, ?eff, Abulk ... that are defined in bsim3v3, however, it is really hard to calculate such parameter values by hand, coz all of the equations involve too many other (...)
Hi everyone. someone who used to design "Analog" IC,for example, Opamp, using bsim3 know a truth that every mosfet in the circuit has been "saturated". if not, the circuit is not work properly. bsim3v3 is very accurate Mosfet model. bsim3v3 have 132 ( is it right? ) parameters and saturation current (...)
What is ξ, and how to obtain it from bsim3 parameters?
go to the berkeley website. there are a lot of model equations of bsim3v3 and bsim4
You can get them by your device size and parameters(cgxo) from model file. For hand calculation such results are acceptable, however, if you don't satisfy such accuracy, you need know much on Cap modeling which is complicated in modern device models such as bsim3.
I think you can do some hand calculations since bsim3 still provides the parameters. I suggest you read the HSPICE MOSFET Models Manual carefully and try to figure out how to calculate u and Cox.
1) the Hspice level 49 is the bsim3 modelling for the MOSFET alone!!!!!!! it is the complete large signal model only!!!!...hspice will derive the small-signal model from the large signal model parameters in the model file and bias condition (which u set up). 2) you dont use the 100's of equations when doing design...the complicated models (...)
go to cadence pspice site and download from there a utility that converts hspice bsim3 models to pspice ones. It is free to download.
in my opinoion bsim3 v3 has complex model for calculation of lambda but rd= (lambda*Id)^(-1) also remain valid for for first design guess though for actual lambda one can use simulated response of transister. and for perticularly answer original query i don't think lamda value in practice ever exceed unity. though in some transister reg
