Design of A Low Power Low Voltage CMOS Opamp

open access: yes, 2010
In this paper a CMOS operational amplifier is presented which operates at 2V power supply and 1microA input bias current at 0.8 micron technology using non conventional mode of operation of MOS transistors and whose input is depended on bias current. The

Design and Characterization of a Self-Oscillating Fluxgate-Based Current Sensor for DC Distribution System Applications

open access: yesSensors
Fluxgate-based current sensors are usually implemented for DC current detection, but their complex structure and circuits with large volume and high cost have been limiting their applications.

A 0.3-V 98-dB Rail-to-Rail OTA in $0.18~\mu$ m CMOS

open access: yesIEEE Access, 2020
A new solution for an ultra-low-voltage, ultra-low-power operational transconductance amplifier (OTA) is presented in the paper. The design exploits a three-stage structure with a Reversed Miller Compensation Scheme, where the input stage is based on a ...

A Standard-Cell-Based CMFB for Fully Synthesizable OTAs

open access: yesJournal of Low Power Electronics and Applications, 2022
In this paper, we propose a fully standard-cell-based common-mode feedback (CMFB) loop with an explicit voltage reference to improve the CMRR of pseudo-differential standard-cell-based amplifiers and to stabilize the dc output voltage.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Influence of plasma arc welding heat treatment on microstructure and magnetic properties of 1J85 permalloy welded joints

open access: yesCailiao gongcheng
This study addresses the issue of magnetic property degradation during the welding of 1J85 permalloy. Comparative experiments are conducted on 1.5 mm thick annular 1J85 permalloy using two processes: plasma arc welding (PAW) and plasma arc heat treatment

Formation of Low Threshold Voltage Microlasers [PDF]

open access: yes, 1992
Vertical cavity surface emitting lasers (VCSELs) with threshold voltages of 1.7V have been fabricated. The resistance-area product in these new vertical cavity lasers is comparable to that of edge-emitting lasers, and threshold currents as low as 3 mA ...

Charge transport through weakly open one dimensional quantum wires

open access: yes, 2008
We consider resonant transmission through a finite-length quantum wire connected to leads via finite transparency junctions. The coherent electron transport is strongly modified by the Coulomb interaction.
