Design and Verification of Low Power High Speed Voltage Level Shifter Based on Pass Transistor Methodology
Abstract: This study explains how a voltage level shifter (LS) can be built using a Wilson current mirror level shifter (WCMLS) with a mirrored output. The proposed fix avoids WCMLS's typical issue of requiring a mirror with a size ratio that is too large. It's a space- and cost-saver. The proposed LS requires less components than its modern versions and uses only tiny components, taking up even less space. The proposed …

SYMMETRY AND ASYMMETRY MODEL FOR THERMAL CONDUCTIVITY IN POROUS MEDIA
Abstract: This paper focuses on determining thermal conductivity in porous media using symmetry and asymmetry models. Since porous media are not uniform and homogeneous in most of the cases, anisotropy must be taken into account, what derives in the application of an asymmetry model as thermal gradients are not equal in all directions. The paper demonstrates that, under certain conditions, isotropic conditions, therefore, symmetry model can be applied to non-homogeneous or …
