Dear all,
I am designing trimming bandgap reference. The trimming range, or trimming bit is identified from the 6-sigma monte carlo simulation. What I mean is, the worst case of monte carlo simulation results can be trimming fallen within the spec.
but how can I guarantee the tempco meet...
Hi Dick_freebird, i quote your comments below.
YOU: With a two-resistor trim you only need to measure two temps
because you don't have the access to do anything about
curvature.
ME: This is the well-known first-order compensation technique. Is this enough to achieve 30ppm performance in...
I am working on the trimming bandgap reference design, the target performance is 30ppm.
Some questions need help from experienced designer, thanks so much.
1. Generally fomular for Vref output, Vref= (R2/R1) * (lnN) + VBE. Someone mentioned that adjusting R1 to trimming TC, the reason behind...

I have the same question with the poster. But my cadence version is IC5141(sub_version : 5.10.41.169)
Would you please clearly advise me how to solve this problem? I have stuck at this quesion for one whole day.
thanks.
Dear friends,
I just finished the installation of cadence IC5141 base (it appears : sub-version 5.10.41.169 when start the icfb after installation).
When I start artist analog simulation , it is reported "Waveform type must be specified if any waveform parameters are given".

I need to generator single tone four phase for testing my chip from one input signal. I browse many webpages without any finding. Any suggestion are welcome . thanks.

For my opion, I will not resign my job. Experience is so important. Signal processing is not so hot. No many positions are waiting for your after you finish your msc course.
By the way, I am in HongKong.

Has anybody already downloaded it? I am urgent to get it. I am a student on this field. Your generosity is really appreciated. thanks.
If you use hspice simulator(you can choose simulator in cadence enviroment if you have such license), you can run simulation directly with hspice model. Otherwise you need spectre model, which is quite different format from hspice.
