Abstract: This article presents a type-II sub-sampling phase-locked loop (SSPLL) that achieves low jitter, low spur, and sub-$\mu $ s locking time when synthesizing millimeter-wave (mm-wave) ...
Abstract: An electrochemical zinc oxide (ZnO) pH sensor is proposed and prototyped using a flexible printed circuit board (FPCB). The device is resistant to acidic and alkaline solutions and exhibits ...
