A class D amplifier is basically a category of amplifier in which the power devices (mosfets and BJTs) are operated like switches. The associated output devices in such amplifier circuits either turn fully ON or fully OFF, but never switch between other undefined levels ensuring minimal heat dissipation and maximum efficiency from the devices. The […]
