hello,guys:
I am using ADS the design guide-amplifier-DC and bias point simulation-FET_ft_fmax_vs Bias cell to simulate the Fmax variance with the sweep of VGS and VDS. when I use the original schmatic with original ideal GaAs FET, this cell works and I can get the results like below:
but when...
also, do I need to write the spice to describe the detailed circuit and run the simulation with ocean or I could only use the ocean to finish all the things that I mention above?
thanks for your reply. for your message:Cadence ADE has an optimizer and if you define W and L dimensions as variables, it will find the optimum ones for a defined target. how about the bias voltage. could this tool also set the bias as the parameter? and is this tool only find the target value...
hello, guys,
I used to simulate the analog circuit by clicking the GUI provided by IC616 and mmsim14. I find it's such a burden to simulate the same circuit for so many times. for example, if I design a specified OTA including only 9 mosfets and 2 capacitors. I have to adjust the...
hello, guys
I am trying to integrate ansys Electromagnetic Suite 16 into cadence. I have installed Ansys Electromagnetic Suite 16 and the ECAD (which is the interface to the virtuoso) and do exactly what the configure says as follows:
1)Initial Setup
a) Environment variable settings...
hello:
I have acquired the physical parameters of MOSFET from TSMC PDK model XXX.scs file.
it appears like this:
model nch bsim4 {
1: type=n
+ lmin=9.999997e-006-(dxln+dlmisn) lmax=2.00001e-05
+ wmin=1e-005-(dxwn+dwmisn) wmax=0.0009000001...
hi guys. when i install hfss, everything goes well but libXext.so.6: undefined symbol: _XGetRequest problem. its like:
Running first-time configuration...

hi guys, i have install ic5141 on ubuntu 14.04 and it worked well when i just installed it. but for some reason,i use ic616 more frequently. after some weeks, i restart ic5141,and i can not get into CIW.
just like picture.figure 1 flashs and last for 2 second,then stay on figure 2 for 1 second...
hi,
i install hspice H-2013 version,i try to simulate the character of simple NMOS in tsmc65LP tech. in the Pdk, i can't find the .lib file which i can find in smic130/180nm. the only thing i can find is .l file(it seems most like a lib)
my netlist as follow:
.title simple_nmosrf_gm_id
.param...
