Abstract -- The diode operated in forward-biased condition has
been 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
circuits (ICs). This work presents new ESD protection diodes
realized in the octagon, waffle-hollow, and octagon-hollow layout
$ R7 z" Y% t' Z1 j! h' t5 qstyles to improve the efficiency of ESD current distribution and
to reduce the parasitic capacitance. The new ESD protection
diodes can achieve smaller parasitic capacitance under the same
ESD robustness level as compared to the waffle diode. Therefore,
the signal degradation of GHz RF and high-speed transmission

不知道这种形式的ＩＯ有没有经过测试，实际的效果和预想的有多少的差别，thanks!
