... AMO-DPWM transmitter using a single supply. An ideal Class-E PA model [9] was used to get these results. When DPWM provides 6-dB power back-off, no more than four duty cycles (23%, 27%, 32%, 50%) are necessary to get high efficiency. As shown in Fig. 5, this DPWM approach can also be combined with a ...

Buck converter



A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
