What I didn't get in the article is how this produce constant negative voltage.
From what I understand with my low amateur electronic skills, this would produce a scare signal with -5V/0V, at whatever quick pace.
That would average at -2.5V if we put a low pass filter.
This would work for me with 2 charge pumps, but I only see one large capacitor
- kens 6y agoThe substrate has some capacitance to hold the voltage steady. The diode blocks the 0V so the substrate only "sees" the -5V.(It acts as a peak detector, not a low pass filter.)
