A multivibrator-driven voltage multiplier raises MOSFET gate voltage under reverse battery polarity so the switch stays conductive and the device remains powered.
A blocking diode, DC supply, and bias capacitor hold wafer-to-chuck voltage below damage thresholds during high-voltage plasma pulsing.
Integrated high-voltage pulse channels and safety monitoring enable portable neurostimulation with customizable output while preventing timing faults and tissue damage.
