Join DesignCon in this webinar series presented by expert engineers from the electronics chip, board, and system industries. The sessions will walk through use cases, propose various tools for solving a range of design problems, and expand your understanding of key engineering principles.

Power Integrity: Analyze Impedance to Improve Power Delivery, SI & EMI Power Integrity is all about delivering the appropriate power to maintain the Signal Integrity of dynamic loads. All with power delivery design margins that allow for reliable product performance. The key challenge for the PI engineer is that the dynamic load can operate from DC to GHz resulting in extreme bandwidths of power delivery and the potential for EMI. Target Impedance vs. frequency is a great tool for designing for power delivery over the full bandwidth of the dynamic load, but designers often fail to use its full benefit. This webinar will cover the basics of target impedance, and then go beyond to show the benefits of advanced impedance analysis techniques for power delivery.

When you watch this webinar, you will:

  • Learn how to reverse engineer target impedance to generate requirements for the VRM’s active inductance and the load’s package/die capacitance;

  • Watch how flat impedance design improves design margins over component tolerances and avoids the disaster of a rogue voltage wave arriving at the load;

  • Explore advanced PI ecosystem time domain simulations with EM PCB models to understand Power Supply Rejection Ratio (PSRR) and the potential sources for conducted EMI.
