When it comes to analog circuits, the layout phase following the schematic design can feel like an afterthought. By bogdan adamczyk and jim teune in emc concepts explained I understand that the adjacent trace will distort the signal on my original trace with noise, especially at high power or high frequency, which i assume is the point, but i need to calculate the actual capacitance.

Although you can’t extract parasitics directly, you can determine the behavior of parasitics in circuit diagrams, and you can extract parasitics from test and measurement data from real circuits
Read on to understand the role played by spice simulators in extracting parasitic circuit elements.
Electromagnetic interference (emi) refers to unwanted electromagnetic noise that disrupts neighboring devices or systems These trace parasitics can affect the characteristics of an analog filter, or noise coupled from digital signals can negatively affect the behavior of a sensitive analog signal. Successful circuit designs using high−speed amplifiers can depend upon understanding and identifying parasitic printed circuit board (pcb) components Simulating a design while including pcb parasitics can protect against unpleasant production surprises.
These parasitics can degrade signal integrity, cause electromagnetic interference (emi), and lead to unexpected circuit behavior A critical question in pcb design is whether these parasitic components can be accurately simulated before fabrication.
