In the spec for LT1533 (Linear Technology switching regulator) is shown
the device should have 25nH inductance between the ground pin and the
GND. According to my calculations a microstrip line with W=7 (H=5, T=2.8
Er=4.3) has app. 6.5nH/inch. So to get a 25nH trace one would need to
3.8inch long trace.
Q1: Is there a trace configuration that I could use to create a 25nH
inductance that would not be so lengthy and in the same time would not
as an antenna?
Q2: Is my calculation (app 6.5nH/inch) correct?
