Abstract
In this paper a class-D audio amplifier for mobile applications is presented realized in a 0.14μm CMOS technology tailored for mobile applications. The amplifier has a simple PDM-based digital interface that requires only two pins and enables assembly n 9-bump WL-CSP. A reconfigurable ate driver is used that reduces quiescent current consumption and radiated emission.
