App note: Passives aren’t really So Passive: PCB


The last part of “Passives aren’t really so passive” series app notes from Maxim Integrated discusses about PCB flaws that can lead to passive errors to IC performance. Link here (PDF)

Active components like transistors and integrated circuits change signals using energy from the power supply. However, passive components like resistors, capacitors, inductors, and connectors actually can, and do, change the signal in unexpected ways. This happens because all these passive components contain parasitic components. This application note, discusses printed circuit boards and the errors that can occur because passive components aren’t really so passive.
