PWM relays allow engineers to go beyond simple "on-off" control to realize significant power savings and reduced heat ...

Abstract: This article introduces Doherty active load modulation into low-noise amplifier (LNA) designs to dynamically enhance linearity. Under nominal small-signal conditions, the proposed LNA ...

Abstract: Camera-based contactless monitoring of vital signs, also known as imaging photoplethysmography (iPPG), has seen applications in driver-monitoring, perfusion assessment, affective computing, ...
