Design Parameters Important for Optimization of Very High Fidelity PWM (Class D) Audio Amplifiers
Class D switching amplifiers can, if optimally designed, achieve performance results, both electrically and acoustically comparable to the very best Class A units. Design parameters and steps needed to achieve these results are considered in detail. Data are presented showing at least seven critical design criteria must be set if high performance is to be obtained. Failure to implement any one of these seven will result in a pwm amplifier of moderate to poor performance, and one that is likely to be subject to considerable spreads in production.
