Goal

The desired result of this IPRO was a survey of the potential applications of class D amplifiers in the field of low-power audio devices. As this was a purely research IPRO, the exact results of our work were impossible to determine, but may include any of the following:

• A list of commercially available class D amplifiers along with their suitability in various applications
• A comparison of commercially available class D amplifiers with traditional class B and AB amplifier offering of comparable type.
• A list of outstanding issues or necessary developments discouraging the use of Class D amplifiers in low-power audio applications.
• Design and build a class D amplifier using conventional circuits/subsystems .
• Test the class D amplifier.
• An analysis of a scratch-built class D amplifier and/or a description of issues preventing the construction of such an amplifier with available resources.
• A list of specific improvements or specifications for class D amplifiers to improve performance in low-power audio applications.
• Other relevant documentation to be used in the further development of low-power audio devices.
