I'm trying to debug some noise I'm seeing on a half bridge and using one of TI's technotes, and I'm a bit confused: https://www.ti.com/lit/an/slla385a/slla385a.pdf?ts=1610328216837
I'm trying to replicate the example, and the math isn't working for me. Seems like it should just be algebra, but I'm not getting anywhere near 7 Ohms (or really 8.4 Ohms). I'm guessing I'm not defining ω correctly? Or it may be my units? I get Ls as 0.0000002148632291
Can you please help provide help on how the math works in the example to get ~8.4 Ohms?
