A novel ESD protection design for radio-frequency (RF)
differential input/output (I/O) pads is proposed and successfully

an ESD bus and a local ESD clamp device are added between the
differential input pads to quickly bypass ESD current, especially
under the pin-to-pin ESD-stress condition. With 10.3-mW power
