Power distribution in PCBs is the foundation around which all things work in the circuit. If this is not designed correctly, the entire circuit is at risk from noise and signal integrity issues, to say nothing of the severely increased possibilities of EMI. Low impedance in the structure, across the harmonic frequency range of a digital circuit is critical. A number of subtle layout techniques will have major impact on power bus impedance, inductance in particular. This 3.5-hour course will cover power bus target impedance, inductance of vias, planes and capacitors, mounting inductance of capacitors, energy delivery to IC cores, the “Bandini Mountain,” best mounting of capacitors based on board stack-up, the importance of IC pinout, placement of decoupling in both low-layer-count and high-layer-count boards, real performance of capacitors (vs. myth), how much decoupling, multiple capacitor values, how to minimize anti-resonant peaks, ferrites in the power bus, analog and RF decoupling, the importance of power/ground plane pairs, ultra-thin power and ground plane pairs and the importance of board stack.
