Researchers from MIT and elsewhere have designed a novel transmitter chip that significantly improves the energy efficiency ...

This paper discusses various ways to take advantage of semi-digital FIR filters (or FIRDACs) in highly digital RF and millimeter-wave transmitters. FIRDACs combine in a single block digital-to-analog ...

In order to continuously power movable sensors, we present an autotracking continuous-wave time reversal (TR) wireless power transfer (ACTR-WPT) system of a novel low-profile planar transmitter. The ...
