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: github.com/YetAnotherElectronicsChannel/Discrete-P… 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.
