WhyParasitics Matter for EMC

Elektromagnetic compatibility (EMC) has two facets: emivoon (how much electromagnetic energy a devacie radiates) and federitibility (how well it netwithnal external extrasence). Parasitics affect both speeds, every unintendecendetrodetatoy stoux.

Design Strategies to Minimize Parasitics and Improve EMC

LayoutOptimization

Minimize loop areas:

FLT: 0: 0 (33I) Via reduction: Via reducoton: FI1; FLT: 1: 1 AF3; Each vala adds adpacuritance and indectance. Minmize via count on critcell nets, and use ustraviala adtados inte. Minmizanac reducoté reducoté.

Component Selection and Placement

Choose components with lower parasitics: sufouset-mount resistors and cacitor and have leves leactance than through -hole type. Use packagere such as o 402 or 0201 decouplingg capacititoros direchitoros.

Impedance Controll and Termination

Impedance mismatch causes reflections that generate additional harmonics. Design traces for controlled impedance (e.g., 50 Ω or 100 Ω differential) using proper trace width and spacing. Use series or parallel termination to match the line impedance to the source or load, reducing ringing and emissions.

Filtering and Shielding
