Abstract
A Class D amplifier comprises a pulse width modulator and an output stage. In this paper we analyze the power dissipation mechanisms and derive the overall power efficiency of the output stage realized using the finger and waffle layouts. We compare the relative merits of these layouts; we propose two design methodologies to determine the aspect ratios of the transistors in the output stage for optimum power efficiency (optimum for a given...
