摘要： An ESD circuit is connected to a power pad and a first node. The ESD circuit includes a RC circuit and a first ESD current path. The RC circuit is connected between the power pad and the first node. The RC circuit is capable of providing a first control voltage and a second control voltage. The first ESD current path is connected between the power pad and the first node. When the power pad receives a positive ESD zap, the first ESD current path is turned on in response to the first control voltage and the second control voltages provided by the RC circuit, so that an ESD current flows from the power pad to the first node through the first ESD current path.
