Claim 10:
11. A method of driving a high-voltage switching circuit, the method comprising:
providing a high-voltage semiconductor switch comprising:
a first switch subcircuit comprising one or more FET circuits and a first voltage-shifting FET, wherein a first FET circuit of the first switch subcircuit comprises a first FET and a second FET;
a second switch sub circuit comprising one or more FET circuits and a second voltage-shifting transistor, wherein a first FET circuit of the second switch subcircuit comprises a third FET and a fourth FET;
wherein each of the first FET, the second FET, the third FET, the fourth FET, the first voltage-shifting FET, and the second voltage-shifting transistor comprises a gate, a drain, and a source;
wherein:
the gate of the first FET and the gate of the second FET are connected to a gate terminal of the first switch subcircuit;
the gate of the third FET and the gate of the fourth FET are connected to a gate terminal of the second switch subcircuit;
the source of the first FET, the source of the second FET, and the gate of the first voltage-shifting FET are connected; and
the source of the third FET, the source of the fourth FET, and the gate of the second voltage-shifting FET are connected; and

the high-voltage semiconductor switch further comprising:
an input terminal connected to the drain of the first FET and the drain of the fourth FET; and
an output terminal connected to the drain of the second FET and the drain of the third FET,

applying a first voltage to the input terminal, wherein application of the first voltage to the input terminal causes
switching of the first switch subcircuit to conduct by applying the first voltage to a first and a second terminal of the high-voltage semiconductor switch, when the first voltage is an enable signal that causes the first FET, the second FET, the third FET, and the fourth FET to conduct; or
switching of the first switch subcircuit to not conduct by applying the first voltage to the first and the second terminal of the high-voltage semiconductor switch, when the first voltage is a disable signal that causes either the first FET, the second FET, or the first FET and second FET to not conduct and causes either the third FET, the fourth FET, or the third FET and the fourth FET to not conduct.
