METODO Y APARATO PARA EL CONTROL DE UNA VARIEDAD DE INTERRUPTORES QUE ESTAN ACOPLADOS PARA UN ESTADO DE BAJA POTENCIA DE SALIDA.

摘要

Power consumption of an output stage such as a class-D output stage may depend on the amplitude and the activity of the signal being output. Here, control signals may be generated to independently control coupled switches of the output stage and to provide a tri-state control scheme for the output stage. These control signals may be generated based on durations of different levels of an input signal over one or more periods of time.
