● IC's power and ground pin bypass CAP and fan-out 在類比與數位會有所不同，bypass cap主要的
功能，將high-frequency noise short to ground。
fan-out via 如下圖
1.bypass cap ground via距離PAD 越近越好。
2.power via between power pin and cap pad for analog. (B)
3.power trace route the power pin to the bypass cap pad before for digital. (A)
