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

with the proposed ESD protection design has the human-bodymodel (HBM) ESD robustness of 3 kV, and exhibits 18-dB power gain and 2.62-dB noise figure at 5 GHz. Experimental results have demonstrated that the proposed ESD protection circuit can be co-designed with the input matching network of LNA to simultaneously achieve excellent RF performance and high ESD robustness.
