Abstract

See full text

A hybrid class-H/predictive class-G switching amplifier architecture and techniques for amplifying a signal (e.g., an audio signal) using such an architecture. One example method of amplification generally includes delaying an input signal to generate a delayed version of the input signal, amplifying the delayed version of the input signal with an amplifier powered by a boost converter, and selectively controlling the boost converter to operate in at least one of a predictive class-G mode or a class-H mode, based on a magnitude of the input signal.
