Hi. I am trying to implement a cmos half-adder in ltspice but I am not sure what parameters shall I use for the pmos and nmos. Are their available mosfets in the market which have LTSPICE parameters? So that I could simulate the half adder using real mosfets. Please help. Thanks.
I have used the asu library, but I don`t know whitch of the models in should I use. I used bulk-cmos model generated by online tool in nano-cmos part of asu website. But I don`t know how to get technology specifications like Leff, Tox and Rdsw.
help i am doing analog ic design using 0.6um cmos Bulk process.tell me the process with calculation method... Threshold voltage? Transconductance parameters in saturation? Bulk threshold parameter? Channel length modulation? Surface potential at strong inversion?
I followed the AWR manual for importing the netlists to AWR. You have to add additional commands so that AWR can parse the model parameters. Try importing the TSMC 180nm model parameters with the .subckt command shown below. It worked for me. I have added flicker n
The phase noise plot obtained for a Ring VCO for TSMC 180nm technology is shown below. This was obtained after adding the following cmos parameters with noise parameters added; .MODEL cmosP PMOS ( LEVEL = 49 +VERSION = 3.23 TNOM = 27 TOX = 4.1E-9 +XJ = (...)
Which parameters do you need? Try PTM Nano-cmos.
The latency and rise /fall time of each gate affects these parameters. IF you design looks like this then it is typical for most

Hi guys, In cmos Circuit Design, Layout and Simulation by R.Jacob Baker page 300, Table 9.2 shows the parameters for short channel MOSFET. These are the parameters given: Id = 10uA Vgs = 0.350V Vth = 0.280V Cox = 25f F/um^2 W = 2.5um L = 100nm I'm trying to calculate back using Id equation and the parameters (...)

Hi every one, I want to design an amplifier in cmos 0.18 tech with this parameters: gain: 20dB-30dB bandwidth: 8GHz-9GHz could you please suggest me a circuit? with warm regards Matin :)
In old cmos processes, where the square law was a good approximation, vdsat should indeed be equal to vgs-vth when the transistor is in strong inversion and channel modulation can be ignored (long L). In your case the transistor is in moderate inversion as vgs is almost equal to vth. Try to make vgs a little higher and then re-check vdsat. In moder
Hi, i have designed a LNA using cadence 0.13um cmos technology with bandwidth of 4-6 GHz. My dc and sp simulation run well but my pss simulation keep terminating and show me there is an error. Can anyone please help? I have attached the related images104761104762104763 here.
Hi, I want to simulate NMOS and PMOS noise behavior in 130nm technology with Mentor Graphics tool, parameters as below: Vds=0.7V Id=185uA W/L=100/0.4 um in order to get Id=185uA, Vgs has to be set around 0.36V. I put a AC voltage signal with offset 0.36V, magnitude default is 20mV. The problem is, when I simulate AC noise behavior, my n

This Source degeneration Gm-cell with negative-impedance-compensation(NIC) technique is used to design loop-filter for 2nd order Sigma Delta ADC. I dont know what are the parameters/specifications needed for the design of the ADC. Also i need input parameter values like Vsin, Vref, Vss for this Source-degeneration Gm-cell. I am using Cadence 180nm
what are the parameters of cmos schmitt triggar?
it seems you are posting several queries on cmos schmitt triggers have you looked at the application notes, or articles on them?
Today we use some complex model such as BSIM3 to describe the short-channel cmos behavior. In an actual design, we need some parameters to do handcalculations. I see some methods to extract simple large signal model from the computer model. I'm confused about this. Don't these short-channel models have the particular parameters for (...)
I don't know your process, but if it is a bulk cmos probably the devices ending with "3" are triple well fets with 6 terminals. Your pdk provide devices with 3 different threshold voltages. _lvt for lower, _hvt for higher Vth and standard ones. I don't know what _nat means but it could be the same as standard fet. To found your PDK location chec

Hi, I am simulating RF self-biased cascode power amplifer in Cadence under the paper below: A 2.4GHz, 0.18?m cmos self-biased cascode power amplifier. (attached below) My problem is that the output voltage, Vout, is even smaller than input voltage, Vin. Meaning that it doesn't amply at all even attenuate input signal. Could anyone help? Here i

Hi everyone. I want to design a power amplifier and I need a ams cmos C-35(nmos MN1) for my design,but I can't find it in ADS library.what should I do?
Perhaps these Predictive Technology Models (PTM) may help you: click Nano-cmos, then change to your process size. Here - if need be - you can still adapt some parameters, then click Submit. Now you can download NMOS worst-case, typical, and/or best-case model parameters. Same procedure for
No display means, no post screen? If so may be tables are corrupted in cmos. So remove the battery and leave it out for a while and then insert it back, if it works than use default parameters, set date and time etc, save it and than boot it. If other problem than check power supply voltages etc. Hi, Im usually using Intel
Hi guys, I'm trying to design a neural recording amplifier with some crazy specs (in my opinion at least and unfortunately I'm pretty unexperienced). The task is to amplify amplitudes as low as 1 ?V (up to some mV) while having a bandwidth of 50 kHz. Furthermore the bandwidth, gain and noise should be tunable depending on the application. Oh and t

Hi everyone, Is there any way to use gm/id design methodology for switched cap circuits design ? I mean could it be used to design a cmos switch (in triode region) ? if so then what are the required curves to be generated ? if not then is there any other similar technique that can be used ? you know, hand calculations in submicron technologies ar
Hi, I woulgd know what is your operative method to design cmos circuit. For example Allen Holberg is a good book for opamp design, but in the "real world" we don't have kn or lambda or VTH0...So, what's your method? For example for a differential stage, you try with parametric simulation knowing that the current mirror and the current generator d
