1. An electrostatic discharge (ESD) circuit connected to a power pad and a first node, the ESD circuit comprising:

  • a RC circuit connected between the power pad and the first node, wherein the RC circuit is capable of providing a first control voltage and a second control voltage; and

    a first ESD current path connected between the power pad and the first node, wherein 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.
