- This article explains the purpose of the low-pass filter components in Class-D amplifiers and how to calculate their values
- One trick.
Place voltage source with AC magnitude = 1V in series with output between output and load. Do AC analysys and measure current flowing though output terminal – Iout.
The output impedance Zout=1V/Iout. - Why we have to satisfy metal density in layout.
- some thing about the opamp’s noise performance
