Design of a Class-D Mid-Range Amplifier

Objectives - Design a Class D mid-range amplifier to produce audio signals at mid-range frequencies using the digital audio MOSFETs and digital gate driver ICs. - Use 3-level PWM as the modulation scheme. - The output power should be an appropriate industry standard value to drive a 8 ohm driver. - Design a power supply to drive the amplifier. - Assemble design on circuit board. - Test the system. Implementation - Filter the audio signal to remove bass and "top-end" frequency signals. - Amplify the mid-range frequency signal using a voltage amplifier. - Use the IRF6665 Digital Audio MOSFET and IRS20124 Digital Gate Driver or similar components to design a Class D amplifier to amplify mid-range frequency signals. - A 3-level PWM is to be used as the modulation scheme. - Design a power supply to deliver the required power to the system. - Design must be tested for power output, gain, frequency response, stability and harmonic distortion. - Designed must be mounted on a PCB The circuit design and PCB layout must be provided along with any calculations for justification of components. Let me know if it is possible for you to do a methodology with discussion, results and conclusion.
