Designed by Cirket open-source hardware in China, the ESP32-DIV V1 is a handheld wireless pentesting and experimentation tool ...

Abstract: Next-generation wireless networks are expected to utilize limited radio frequency (RF) resources more efficiently with the aid of intelligent transceivers. To this end, we propose a ...

RF front ends are advancing through the integration of high-frequency passive networks with increasingly efficient active devices engineered for ultra-wide bandwidths and constrained power envelopes.

Abstract: This paper proposes a wide-load-range low-dropout regulator (LDO) using a rail-to-rail CLASS-AB CMOS buffer. This buffer enables the output-pole-dominant (OPD) LDO to support a broad load ...
