A Complementary Recycling Operational Transconductance Amplifier with Data-Driven Enhancement of Transconductance [PDF]

Electronics, 2019
An improved operational transconductance amplifier (OTA) is presented in this work. The fully differential OTA adopts the current recycling technique and complementary NMOS and PMOS input branches to enhance the total transconductance. Moreover, in order to achieve higher current efficiency, a data-driven biasing circuit was developed to dynamically ...

Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

Physics‐Based Compact Modeling of Advanced 3D Nanoscale Vertical NAND Flash Memory

Advanced Electronic Materials, EarlyView.
For advanced 3D NAND flash memory, a unified compact model for SPICE is proposed that spans from the intrinsic unit cell to the full string and captures the electrostatic coupling with adjacent inhibit strings. It can successfully predict read behavior, program/erase dynamics, and interactions between neighboring cells, reflecting array‐level behavior ...

High‐Performance and Environmentally Stable Organic Electrochemical Transistors Enabled by a Reprocessed Self‐Doped PEDOT Channel

Advanced Electronic Materials, EarlyView.
A simple reprocessing strategy based on freeze‐drying and re‐dissolution is introduced to enhance the electrical performance of self‐doped PEDOT while preserving its intrinsic environmental stability. The reprocessed S‐PEDOT enables organic electrochemical transistors with improved drain current, transconductance, and robust operation under high ...
