As you probably know, in many occasions LTspice cannot take advantage of multiple CPU cores because many operations are not easily parallelizable. In fact, most simulations I make use less than 20/25% of CPU (intel i5, 4 cores/8 threads). However, running more processes of LTspice to execute different simulations at the same time should overcome this limitation: each simulation is distinct...

New recipes for origin of life may point way to distant, inhabited planets https://www.sciencedaily.com/releases/2023/09/230919155043.htm Summary: Life on a faraway planet -- if it's out there -- might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. Scientists have now exploited those limitat...

Could some electronics guru please help ? I am looking for a very low(few milliVolts) VTO commercially available NMOS, and its corresponding PMOS. I am trying to use a reverse biased photodiode(very low output current) to trigger a PMOS. The output voltage could then be used to trigger ideally a BJT. Any hints, suggestiosn would be greatly appreciated. Thanks in advance.

I tested it because sometimes synchronous switchers make horrendous noise spikes, but this looks pretty good. The trick seems to be to tweak the doping so the substrate diode isn't an SRD.

It's anyone's guess how this will turn out, but rehabilitating America's aging residential structures alone could have an enormous impact. GOP in Congress obstructed and prevented its formation as part of the Inflation Reduction Act, so Biden has to go it alone using presidential authority. Reminiscent of Roosevelt's CCC which would be politically incorrect these days, mainly bec
