How to Determine the Impedance of a Circuit

How to Determine the Impedance of a Circuit

Impedance impacts how signals propagate through the board, how power is exchanged between components, and how signals leak into undesired sections of a PCB. There are several methods for determining a circuit's impedance, but they don't necessarily yield realistic...

How to Reduce Ground Bounce in PCB Assembly

How to Reduce Ground Bounce in PCB Assembly

Ground bounce is a source of noise in a PCB assembly. It is important to prevent this as it interrupts high-speed or high-frequency operation. The major cause for ground bounce is the difference in ground potentials at various points on the circuit. Noise is an...
