Hello AG, I have uploaded the same plotted with the free DPLOT95. It correctly shows the bins. Files > Temp > mc1000_01.gif Files > Temp > mc_distri.asc RUN mc_distri File -> Export Start DPLOT95 Open

Re: Monte Carlo beta and temp on 2N3904
Depending on how Tony did, bin 900 includes 895-905 or 900-910. I would expect roughly 250 or 500 occurences... Cheers AG You are right!... I have never won the lottery. .

Re: Monte Carlo beta and temp on 2N3904
Hello AG, I'll check the data this evening. I strongly suspect the bias issue is "operator error". I quickly threw it together this morning. I exported the plot data from LTspice, and imported it as a

Hello Emmanuel A.Neonakis, You have it. An SMPS-IC with steady-detector is sufficient. Please try this example. Files > Examples > SMPS > buck_boost_efficiency.zip

Re: struggling
Dear Mr Sennewald, Is it necessary that the SMPS-IC from LTC is part of the design, or does it suffice that the IC is just present and trivially connected? If that is the case will you please be kind

Re: Monte Carlo beta and temp on 2N3904
Hi Tony, In 10000 iterations the value 900 never seems to show up.. Is this a binning issue of the histogram or is there a bias in the "MC " function? "mc(val, tol) is a function that uses a random

Re: struggling
Hello Ian, LTspice checks Iave and Vpk when you run a simulation with an SMPS-IC from LTC using the "steady" option in ".tran". If the limit is exceeded, the diode will be marked with a black

Re: Half Bridge IRF7317 or Si4500BDY
Hello Alex, Thanks for your advice, I hope it helps someone. I tried setting Delta to 0 and 1, in the Si4500B example, and confirmed by looking at the data that there was almost no difference. The

Re: Half Bridge IRF7317 or Si4500BDY
Hi Tony. I have for you is good advice. It applies to models of transistors. I recommend to remove the parameter DELTA. This setting adjusts the threshold of the transistor when the transistor width.

Hello Pascal, I don't particularly want to single you out for criticism, even though I obviously seem to be. For each of these devices, the manufacturers provide SPICE models for both N and P channel

Re: Monte Carlo beta and temp on 2N3904
Hello AG, By default, the seed is the same each time, so the MC series is repeatable. However, there is an option to randomise the seed. This was discussed in detail here quite recently; check the
