Is that the circuit that appears in The Art Of Electronics (second edition,
page 372)? If you don't have the book I'll try to describe it: A series
string of MOSFETS where the drive signal is fed only to the gate of the
bottom one, and the gates of all the others connect to a series string of
resistors (each with shunt capacitor) that runs between the drain of the
top MOSFET and the source of the bottom one. Each MOSFET has a gate-source
protection diode.
