dick_freebird,
The reason is that the mismatch parameters from the fab is for "the matching of two identically designed elements located close to each other" and not for interdigitated, centroide or waffle.
My layout will be done interdigitated, centroide or waffle. So I would like to convert...
The matching parameters document provided by the foundry states that these parameters are for "the matching of two identically designed elements located close to each other".
It is logic to think that two large transistors laid out in 3 ways: One close to the other, interdigitated, or...
Re: Monte Carlo runs
Thank you Frankliner. The design is a sample and hold circuit.
If out of 1000 runs, I have, let's say, 50 runs where the output is not stable (oscillates) and the remaining runs result in good Harmonic distortion figure.
Is that considered acceptable or good circuit?
I designed an analog circuit and I am running Monte Carlo analysis.
1. How many Monte Carlo runs are assumed to be sufficient?
2. What of the minimum percentage of successful runs (runs with good results) to consider the circuit is OK?
I designed an analog integrated circuit that samples and holdsthen rectifies a signal.
To measure the quality of sample and Hold I consider THD below half of the sampling frequency.
My question is how to measure the quality of the rectified signal? Any help is appreciated.
purchase cadence
Thank you sreevyas for the information.
there is no Cadence distributor in my country. It is in France. However, I heard they don't sell one license, only bundle.
threshold voltage rel_variation
Thank you kishore2k4. Can you please elaborate more as I am not familiar with statistics? my tool command syntax is as follow:
.param VTH0=gauss(nominal_val, rel_variation, sigma)
if VTH0 nominal is 500 mV, and based on your reply, sigma=1.7mV (0.34% of 500 mV)...
statistical, threshold voltage variations
My simulator doesn't support Monte Carlo analysis as Cadence. However it allows sweeping parameter values that are chosen based on statistical variations. For example, it can vary the threshold voltage VTH using random values chosen by probability...
