The package is QFN. The pin two adjacent's are supply and ground. I see a resistance of 1.75kohm to supply and 100 ohms to ground.
I have done a IV curve for this as well by stepping voltage from 0.1V to 0.5V and its drawing 1m to 5mA of current. So I dont think I am forward biasing the diode.
Hi All,
I am testing my analog chip which is flip-chip'ed on a AlN ceramic interposer and it seems there is a pin which shows 100 ohms of resistance to ground instead of open circuit. The pin is basically the bias diode of a current mirror. The pin is protected by ESD diodes on chip. I have...
Thanks RobG for bring out the subtle differences.
Is there a way to use the MonteCarlo model parameter (or any other model parameter) for dcmatch sim? I fear extracting MonteCarlo parameter for dcmatch would be more time consuming then using trial and error method with MonteCarlo sims to...
Thank RobG and varunkant2k for your replies.
It seems very clear now that dcmatch is a subset of Montecarlo analysis looking at specific parameters. Also I found out that you need specific dcmatch models to perform this simulation. I have access to ST micro and Austria Micro Systems model files...
Thanks Varunkant2k for your reply. Does that mean DCmatch analysis is quicker and limited way of doing Process+Mismatch option of Montecarlo analysis? Because from what I understand the Process+mismatch option gives mismatch variation for matching transistors at various statistical Process...
Hello,
I been reading the User manual of Spectre and came across dcmatch analysis. I tried using the dcmatch analysis on one of the circuit and straight off wasnt really sure how to use it and what purpose it might serve. Tried to read the manual further but didnt get anywhere.
Anybody out...
Here is what Cadence had to say:
Spectre already has an option called "APS" which gives access to enhanced performance without sacrificing accuracy, as well as being able to take advantage of multi-core machines which can give major performance increases overall. It also has capability (early...
Hello All,
I mostly use scripts to do Spectre simulation. We here have a high speed cluster and we would like to leverage it to reduce the speed time of simulation. So I have decided to join a course which uses openMPI or C ( not really sure about the language ) to parallelize the code.
Does...
Hi,
I am using SKILL to run some ac and dc analysis over corners in cadence 5.14. I notice that everytime an analysis is executed there is overhead for calculating Circuit inventory etc.. Since the circuit netlist is same, I assume its a waste of processing time. Is there a way to cut the...
Hi All,
How well is Tyndall National Institute known among Electronic community? Does it have a good reach among engineers? How good is it ranked with respect to other university in terms of RnD?
Thanks
Anil
