·A system-level strategy is presented to achieve high charging efficiency in triboelectric nanogenerator (TENG)-supercapacitor (SC) hybrid devices, with a focus on frequency response design. ·This ...

Because of the widespread use of pulse-width modulation (PWM), the efficiency of a synchronous buck converter operating in this mode is well understood. However, relatively few designers understand ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...
