This study presents an N-port circuit model for $N$ coupled RFID tags, including the coupling effects. The RFID tags are replaced by loaded dipoles. The backsca ...

PID control has been in use for a long time in industry, but only for the past few years has it been introduced into environments such as Arduino, with rather concise libraries and no graphical aids.

Detecting the movement of humans, other animals, or various objects requires the use of suitable motion sensors. This article delves into a specific type of sensor, valued for its unique capabilities ...

The paper proposes a new CMOS passive up-conversion mixer with an adaptive bias circuit providing a building block for the transmitter (TX) in UHF RFID reader devices implemented in system-on-chip ...
