I recently switched phone providers, replacing the SIM chip. Which got me wondering an old wonderment: what's inside? It's remarkable that the industry has standardized on a single form factor and pin out. But I'm curious, what is the separation of functions, between the chip and the surrounding device? How to characterize it as a black box, what exactly are the signals which flow a...

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.

Not as high a max supply voltage as the TCA0372, but that's a big boy slew rate and output current for the price:

LTspice speed

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...
