ABSTRACT:
A high-voltage switching circuit comprising two arms, wherein each arm has a P-channel load transistor, a forward biased diode and an N-channel switching transistor series-connected between the high voltage and the ground. The gate of the N-channel transistor is controlled by a switching signal C in one arm and by the complementary switching signal C in the other arm. Such a structure enables the stress undergone by the load and switching transistors of the switching circuit to be reduced by several magnitudes.
