Peak current and decoupling capacitors during PCB layout Formation of peak current: The current Ioh pulled from the power supply when the digital circuit outputs a high level and the current Iol injected when the digital circuit outputs a low level are generally different, that is: Iol＞Ioh. Take the TTL NAND gate in the following…
