Abstract

Described herein are systems and methods that change trigger thresholds between switching cycles such as to prevent constant switching frequencies from creating noise in the audible range. In various embodiments this is accomplished by using different offset values to adjust threshold values of a comparator circuit to generate non-periodic trigger thresholds that are applied to a wake-up circuit.
