摘要：
A padring formed on a semi conductive substrate die provides Electro Static Discharge (ESD) protection for a Radio Frequency (RF) circuit also formed on the semi conductive substrate die. The padring includes a voltage supply rail, a ground rail, a plurality of signal pad structures, and a plurality of voltage clamps. The plurality of signal pad structures are disposed between the voltage supply rail and the ground rail. Each signal pad structure includes a signal pad that couples to the RF circuit, a voltage supply path diode disposed between and coupled between the signal pad and the voltage supply rail, and a ground path diode disposed between and coupled between the signal pad and the voltage supply rail. The plurality of voltage clamps are disposed between and coupled between the voltage supply rail and the ground rail.
