Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be(More)
In this paper, conducted EMI measurements of two integrated Class D audio amplifiers are realized using the EN55022 standard, in order to compare the EMI behavior of two modulation techniques. The first circuit uses a carrier-based pulse-width modulation (PWM) and the second one uses a self-oscillating modulation based on sliding-mode (SM) control.(More)
