#139 In this video I continue looking at the noise coming from switching converters. I look at the various circuit loops in converters and check which of the loops generates the most amount of noise, so which needs to be kept small when compromises need to be taken.

Previously on Circuit Loops:
SMPS loops: youtu.be/VpUFsBSqUq4
Amplifier loops: youtu.be/XVYgGgp6GqQ
Field probes:
Magnetic: youtu.be/l2YS1s6HxHU
Electric: youtu.be/S27zk_Gj9nU
