How to Make Tradeoffs in PCB Power Design
ByGrace July 30, 2025July 30, 2025
When designing a complex board, you must make certain design tradeoffs. These tradeoffs influence the design of the PCB’s power distribution network. When capacitors are mounted on a PCB, they create an additional loop inductance, which is dependent on the capacitor’s placement. The value of this loop inductance is design-dependent. This loop inductance is determined…
