INCREASING POWER EFFICIENCY IN A DIGITAL FEEDBACK CLASS D DRIVER
Last updated:
Abstract:
Systems and methods are provided for architectures for a digital class D driver that increase the power efficiency of the class D driver. In particular, systems and methods are provided for a digital class D driver having a feedback analog-to-digital converter (ADC) that can have a latency of 1 cycle or more than 1 cycle. A feedback ADC with a latency of 1 cycle or more is significantly lower power than a low latency feedback ADC. Systems and methods are disclosed for a power efficient digital class D driver architecture that allows for a latency of one or more cycles in the feedback ADC.
