current density

r2583614

If the peak current is approximately 2 times the average current, what is the size of the power rails (VDD and Vss) required for these buffers if the allowable current density of the metal layer is 1mA/1 um

若peak current有達2倍之多,那電源metal線需要考慮進去!

7 ]' Y& O- v; u: d3 a- D# _假如1mA/1 um,你的peak current有到3mA,那至少metal要畫到3u以上,
若Area考量,則可以用疊的

謝謝2樓大大的指點，我困擾了很久
