高频下计算过孔对信号的影响
1ns对应的带宽BW=0.35/1ns =0.35GHz,即最高有效谐波分量是0.35GHz。 Z=j*W*L =2*π*f*1.015 =6.28*0.35*1.015= 2.23Ω

原创 PCB的寄生电感
2层PCB设计时候回路的寄生电感计算方式。 由两个平面构成电流路径的回路电感,取决于每个平面路径的局部自感和它们之间的局部互感。平面越宽,电流分布就越扩散开 ...

原创 高速信号回路
You are correct that the length of the via affects its inductance. Not only the length of the via, but also the shape and proximity of the return-curr ...
