Radiation-hardened phase-locked loop (PLL) circuits represent a critical advancement in safeguarding electronic systems against the deleterious effects of ionising radiation.

This study reports a closed-loop system (CLS) for resonant micro-electromechanical systems (MEMS) sensors subject to blue-sideband excitation (BSE) for the first time. Compared with the conventional ...

We introduce a novel wireless sensing technique for gas holdup measurement within the inner draft tube of a loop reactor. A magnetically coupled resonant circuit senses the changes in the permittivity ...
