Hi,
as the divider has to cover very wide freq range(0-2G), I want to use true-single-phase structure to design the DFF. I am not quite familiar with this. It works well for 2G with 0.18um process. Can it support as low as several MHz or KHz? Thanks!
Hi,
To generate a bus of signals as the stimulus, I want to build a veriloga model. the input will be a voltage pwl source which in turn gives the voltage vaule versus time with a transition time. the output will be the corresponding bus value. For example, when input voltage is 6, the output...
verilog-ams examples
if you have both scs and vams, you can try ade with using ams as simulator
which does work.
as for your question, to simualte in command line, I only have experience in using scs only nestlist. the script is like " spectre -arguments *.scs"
ac simulation
hi guys,
what 's the op for an AC simulation?
I mean, when using spectre for ac simulation,
different op means different gm etc. so before ac, simulator must know exact DC right?
then
another question, if I use monte-carlo ac simulation,
will the dc varies as monte-carlo ac...
ams spectre
Hi guys,
I met with a problem when simulating both ams and spectre in ADE because I wanted to save an internal wire in ams.
I want to check the tran voltage of an internal wire, but it seems that it can't be saved and plotted in ADE ( as what we normally do in spectre with...
but, I think , when you design the LNA, (in my case, I use cadence icfb, simulation includes input matching and LNA), considering to some extent the parasitics, the NF you get from simulation is what you will more or less get in the measurement, right?
it is not easy to get pure lna nf since...
and, I have one question,
now in my design, the foundry provides several model of transformers, stacked and interleaved. and they provide the performance parameters.
I wonder how to verify the performance?
in my bench, one port of the primary is connect to 50ohm port (that is the case I will...
Re: die package?
yes, in some cases, especially sensitive to cost , die is directly mounted on the pcb.
after bond all pads of die to pcb pad, the die will be cover with glue ( actually , I don't know how to describe this, since it is one kind of black glue) and then, the whole pcb will be...
hi,
I am not quite clear about "easier requirements for phase..."
do you mean the phase imbalance of LNA will have less impact on the performance than that of amplitude?
then extremely, there are some cases in IEEE paper, that the the positive output of passive mixer is fed the rf signal and...
