ABSTRACT:
A circuit configuration and a method enables less-expensive bipolar switching devices to be employed in high-accuracy class D amplifiers. A constant-bias current is provided between the switching devices of a class D amplifier, and, through feedback or appropriate alternative implementation, the output levels of the class D amplifier achieve deterministic voltage levels regardless of current.
