Design of A Low Power Low Voltage CMOS Opamp
, 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

Macromolecular Rapid Communications, Volume 47, Issue 10, 19 May 2026.We report a nanoparticle formulation strategy for the ladder polymer BBL that enables undoped enhancement‐mode OECTs. Controlled reprecipitation with DBSA yields stable nanoparticles, and spray‐coating forms dense, well‐connected films. The resulting devices exhibit strongly enhanced electrochemical response and transconductance, establishing a ...

Substrate‐Tight Graphene Transmembrane‐nanofluidic Devices
Small, Volume 22, Issue 25, 4 May 2026.This study demonstrates that the covalent coupling of a pyrene layer to a silicon nitride substrate using silane and peptide chemistry increases the adhesion of graphene to the substrate and prevents the delamination of graphene. 76.2% of the devices with free‐standing graphene are successful devices for ion transport measurement in 0.1 M HCl ...

Small, Volume 22, Issue 26, 8 May 2026.High‐temperature reconstruction of c‐plane sapphire during MOCVD growth of MoS2 fundamentally alters the optical and electronic properties of MoS2 epilayer by introducing step‐edge driven interfacial charge transfer. Raman, PL, and KPFM reveal non‐uniform doping and strain in as‐grown films, whereas transferred layers show uniform optical and ...

Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes
Small, Volume 22, Issue 28, 18 May 2026.This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

Small Science, Volume 6, Issue 5, May 2026.Schematic illustration of field effect transistor‐type sensor electrode fabrication and synthesis of MoS2@rGO hybrids. 1T or 2H MoS2 were combined with GO, followed by thermal partial reduction to form MoS2@rGO with defect sites. The removal of hydroxyl groups as moisture increased specific surface area and porous size, enhancing vapor adsorption ...

Thermal Noise Canceling in LNAs: A Review [PDF]
, 2004 Most wide-band amplifiers suffer from a fundamental trade-off between noise figure NF and source impedance matching, which limits NF to values typically above 3dB.

A CMOS class-AB transconductance amplifier for switched-capacitor applications [PDF]
, 1990 A CMOS operational transconductance amplifier (OTA) using a fully differential single-stage core OTA as the input stage and a differential to single current converter as the output stage, each biased at a separate current level, is presented.
