RFIC 的ESD保护

daojx

为什么RFIC的芯片比mixed 芯片在生产测试中容易受ESD损伤呢,有没有RD达人帮忙从芯片设计的角度解释一下,谢谢先!

谢谢daidai的回答,可否告知为啥small capacitance的ESD电路就难设计呢?惭愧,不是很懂哦!

补充一下,RFIC 受ESD损伤的经常是那两个保护diode,是不是RF的diode跟mixed ic 的diode不一样呢?
还有ESD 保护电路是要求IC在有power supply 的情况下才能起作用么?

自己顶一顶,希望达人开开言:
" L7 r, @. P8 {+ k; w; [Providing ESD protection for RF circuits is not trivial, as the parasitic impedance contribution from the ESD protection could degrade the RF functional specifications.

thanks you daidai, I got some files from internet for further explanation, if you are interested, i can upload them here.
