In this video I want
In this video I want to guide you through the design process of a discrete PWM based Class-D amplifier, including theory, simulation, PCB design, measurement results and live speaker testing.
0:00:38 - Amplifier Concept Overview
0:05:50 - PCB Board Schematic
0:11:09 - Class-D Output Filter Simulation
0:12:44 - Small-Signal Analysis of the Amplifier
0:15:57 - Transient Simulation of the Amplifier
0:20:20 - PCB Board Overview
0:22:46 - Basic checks with the Oscilloscope (Power-on-reset, PWM signals)
0:26:37 - Measurements (DC Offset, Gain, Output power, THD)
0:28:17 - Live test with a HiFi Speaker
All documentation (Schematics, Simulation files, PCB design, measurement results) can be found on my GitHub page:

This video is actually intended as a follow-up session of my video no. #2 where I already talked about how to design a discrete Class-D amplifier.
If you still want to get more in detail (especially on feedback-loop-theory), I would propose you to watch this video: • [#2] Designing A Discrete Closed-Loop...
In case, you have further questions, don't hesitate to leave me a PM.
