Abstract
A system level electrostatic discharge (ESD) detection device includes a phase detection unit including at least one phase detector suitable for detecting a phase difference between a plurality of supply voltages or between a plurality of input signals; a storage unit suitable for shifting between a first and a second state, the second state indicating a phase difference detected by the phase detection unit; and an output unit suitable for outputting a system level electrostatic discharge (ESD) detection signal according to the first or second state of the storage unit.
