PCB Design of Low Noise Class D Amplifier

This paper presents a PCB design for a Low Noise Class D Amplifier tailored for Home Theater applications. The circuit components, including cabinets and other modules, were carefully selected to ensure low-noise performance. Power supply and grounding techniques were meticulously optimized to enhance signal clarity. A high-performance Class D amplifier IC was employed to achieve superior efficiency. The PCB layout was precisely designed to minimize noise coupling, thereby ensuring high-fidelity audio output. These optimizations make the proposed design highly suitable for use in home theater systems. Experimental validation and simulation results confirm the design's effectiveness in delivering high-quality audio with minimal distortion.
