Abstract

The market for cellular phones is growing rapidly and cellular phones rank among the most prominent portable devices. All these phones are battery-powered and long use times on a single battery charge are required. The Power Amplifier (PA) draws most of the current from the battery in talk mode. Therefore, a reduction in this current will lead to a significant increase in talk time. This chapter covers powering the PA with the optimum supply voltage for each output power, which leads to a decrease in supply current. As described in chapter 1, this is one of the basic tasks of a Battery Management System.
