A Technique to Reduce the Capacitor Size in Two Stage Miller Compensated Opamp

2018 9th International Conference on Computing, Communication and Networking Technologies (ICCCNT), 2018
In this paper two stage Miller compensated opamp has been discussed qualitatively and quantitatively. A modification to the conventional compensation network has been proposed, which will reduce the capacitor size hence circuit area. Transfer function for the newly proposed solution has been derived and explained the results.

Impact of Interface Traps on Direct and Alternating Current in Tunneling Field-Effect Transistors

Journal of Electrical and Computer Engineering, 2015
We demonstrate the impact of semiconductor/oxide interface traps (ITs) on the DC and AC characteristics of tunnel field-effect transistors (TFETs). Using the Sentaurus simulation tools, we show the impacts of trap density distribution and trap type on ...

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Expandable Nanocomposite Shape‐Memory Hemostat for the Treatment of Noncompressible Hemorrhage

Advanced Science, EarlyView.
A nanocomposite‐coated shape memory foam rapidly expands, accelerates clotting, and reduces blood loss in vivo. Its fast volumetric expansion and strong procoagulant activity make it a promising hemostat for treating deep, noncompressible hemorrhage.
