The Bypass Capacitor in High-Speed Environments
High-speed switching environments generate noise on power lines (or planes) due to the charging and discharging of internal
and external capacitors of an integrated circuit. The instantaneous current generated with the rising and falling edges of the
outputs causes the power line (or plane) to ring. This behavior can violate the VCC recommended operating conditions or
generate false signals, creating serious problems. A simple and easy solution must be considered to prevent such a problem
from occurring. This solution is the bypass capacitor.
