Key Takeaways

  • Signal integrity is lowered when the signal in an IC experiences electromagnetic interference or crosstalk.

  • Crosstalk in an IC can cause signal propagation delay, signal propagation failure, pulse distortions, and emissions.

  • EMI and crosstalk are responsible for poor signal integrity and high noise margins in ICs.

Signal integrity in integrated circuits (ICs) is the ability to propagate the signal from its source to a destination without distortion. In integrated circuits, signal integrity is greatly affected by power supply noise, delays, overshoots, electromagnetic interference (EMI), and crosstalk. The crosstalk in ICs is a type of electromagnetic interference between two signals propagating adjacently. As the EMI and crosstalk in an integrated circuit increases, the system experiences glitches, errors, and timing problems. Let’s explore signal integrity in ICs and how EMI and crosstalk affect this integrity.
