Power Integrity Assessment and Optimization in the Frequency Domain

IEEE MTT-S Latin America Microwave Conference:

Power Integrity (PI) has become the weak link in RF, Microwave, High-Speed Digital and Analog circuits. Often the most significant contributor to phase noise (and jitter), SNR (and ENOB) and EMI, engineers are increasingly pressured to evaluate the Power Distribution Network (PDN), which includes the power supply (or supplies), power planes, decoupling capacitors, ferrite beads, and inductors.

In this session, the author presents an impedance-based approach to PI assessment. The session covers test setup and measurement dos and don’ts for the 1 and 2-port shunt thru impedance tests, VRM and capacitor modeling, control loop and stability assessment and the connectivity options from fixtures to probes and everything in between.

Since many of these components require precise milliohm, or even sub-milliohm measurement, the RF network analyzer with incredible dynamic range and an exceptionally low noise floor is demonstrated.
