A software-defined radio (SDR) transmitter needs a universal modulator and power amplifier to support any modulation in any band. There is a simple solution, namely, a Cartesian I-Q upconverter followed by a linear power amplifier, but for complex modulations its power conversion efficiency is often under 10%. Therefore, the search continues for a more(More)
Bluetooth is a communication protocol enabling low-cost, short-range radio links between mobile phones, mobile PCs, and other portable devices. The Bluetooth standard specifies a 2.4 GHz; frequency-hopped, spread-spectrum system that supports a data rate of 1 Mb/s. This paper describes a low-cost, low-power, and highly integrated solution for 2.4 GHz(More)
Pacemakers have existed for decades as a means to restore cardiac electrical rhythms. However, lead-related complications have remained a clinical challenge. While market-released leadless devices have addressed some of the issues, their pacer-integrated batteries cause new health risks and functional limitations. Inductive power transfer enables wireless(More)
