Abstract -- The diode operated in forward-biased condition has
' c5 n* g' ]' H/ X0 Z0 Ibeen widely used as an effective on-chip ESD protection device at
GHz RF and high-speed I/O pads due to the small parasitic
loading effect and high ESD robustness in CMOS integrated

realized in the octagon, waffle-hollow, and octagon-hollow layout
styles to improve the efficiency of ESD current distribution and
