The manuscript describes the design and implementation of a low-power, fully differential switched-capacitor ΣΔ modulator in STM 90-nm CMOS technology, for sensor interface applications. With the aid of an accurate behavioral model, the power consumption is minimized without sacrificing the effective resolution. Through the optimization of single-stage integrators, with feed-forward summation, and...
Multiple literature reports describe the synthesis of [RSiO(OH)] 4 or [RSiO(ONa)] 4 compounds. Surprisingly, in the majority of cases the OH or ONa groups all lie on the same face of the cyclomers or half cubes. Consequently, it appears possible to couple R containing half cubes with R’ containing half cubes to form bi-functional (Janus) silsesquioxane cages or cubes. We report here...
