How to Design for Power Integrity

Lesson 1 - Finding Power Delivery Noise Problems

How the voltage regulator module (VRM) interacts with the printed circuit board planes and decoupling capacitors within a power distribution network (PDN).

Lesson 2 - Selecting a Voltage Regulator Module (VRM)

Avoid Voltage mode VRMs and shunt compensation for the VRM Error Amplifier. Better performance of a current mode VRM with series compensation for Error Amplifier is demonstrated.

Lesson 3 - Measuring, Modeling, Simulating Capacitors and Inductors

Power supply switching ripple and control loop phase margin are dominated by output inductor and the bulk capacitors. Using accurate RLC capacitor and inductor models is crucial.

Lesson 4 - DC-DC Converter Modeling and Simulation

A measurement-based model can easily be developed. The model supports AC, DC, Transient, HB and EM simulations allowing fast, real-time optimization of the VRM design.

Lesson 5 - Optimizing Decoupling Capacitors

Optimize decoupling capacitors for the best cost vs. performance using flat target impedance design methods. Optimizing this PDN ecosystem allows the lowest noise on the power rail.
