Abstract
An ESD protection apparatus includes a first clamping device and a second clamping device connected in series between a bias voltage bus and ground, and a switch coupled between an input/output pad and a common node of the first clamping device and the second clamping device, wherein the switch is configured such that before a bias voltage on the bias voltage bus has been established, a leakage current flowing through the first clamping device is reduced.
