Claim 6:
7. The electrostatic discharge clamp as claimed in claim 5, wherein:
the N transistors are p-channel metal oxide semiconductor field-effect transistors connected between the power line and the system ground;
the resistor in the capacitor and resistor network is connected between the resistor-to-capacitor connection terminal and the system ground;
the N inverters each have a first bias terminal and a second bias terminal;
the first control terminal of the driving circuit is coupled to an input terminal of a first inverter of the N inverters;
a second bias terminal of the first inverter is coupled to the system ground;
a first bias terminal of an Nth inverter of the N inverters is coupled to the power line;
second bias terminals of a second to the Nth inverter of the N inverters are coupled to output terminals of the first to an (N−1)th inverters of the N inverters, respectively; and
the first connection terminal to the (N−1)th connection terminal connecting the bias units in series from the system ground to the power line are further coupled to first bias terminals of the first to the (N−1)th inverters, respectively.
