Abstract: Class D amplifiers are typically very efficient, making them ideal candidates for portable applications that require longbattery life and low thermal dissipation. However, electromagnetic interference (EMI) is an issue that commonly accompanies theClass D switching topology. Active-emissions limiting reduces radiated emissions and enables "filterless" operation, allowingdesigners to create small, efficient portable applications with low EMI.
