3D Printed Multimaterial Microfluidic Transistors

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce a biocompatible, high resolution photopolymer resin that closely mimics the Young's Modulus (elasticity) and reversible stretchability (no hysteresis) of poly(dimethylsiloxane) (PDMS), enabling the fabrication of microfluidic transistors (i.e., microvalves capable of proportional amplification) by multimaterial stereolithography (mSLA ...

Voltage-Mode Multifunction Biquadratic Filters Using New Ultra-Low-Power Differential Difference Current Conveyors [PDF]

open access: yes, 2013
This paper presents two low-power voltage-mode multifunction biquadratic filters using differential difference current conveyors. Each proposed circuit employs three differential difference current conveyors, two grounded capacitors and two grounded ...

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

open access: yesAdvanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Design and Analytical Study of Strays-Insensitive Switched-Capacitor Filters

open access: yesActive and Passive Electronic Components, 1996
Use of analog circuit elements in active networks have become very common and the demand for their miniaturization is increasing day by day. Though several methods are available for the miniaturization of these elements through large scale integration on

MIMO Switched-Capacitor converter using only parasitic capacitance with Scalable Parasitic Charge Redistribution

open access: yesESSCIRC Conference 2016: 42nd European Solid-State Circuits Conference, 2016
In this work a Multiple-Input Multiple-Output (MIMO) Switched-Capacitor (SC) converter is presented that generates Multiple DC voltages using only the parasitic capacitances already present in fully-integrated SC converters. In combination with the Scalable Parasitic Charge Redistribution technique, the presented MIMO converter can provide voltage ...

Estimation of background carrier concentration in fully depleted GaN films

open access: yes, 2015
Buffer leakage is an important parasitic loss mechanism in AlGaN/GaN HEMTs and hence various methods are employed to grow semi-insulating buffer layers.

Resonance circuits for adiabatic circuits [PDF]

open access: yesAdvances in Radio Science, 2003
One of the possible techniques to reduces the power consumption in digital CMOS circuits is to slow down the charge transport. This slowdown can be achieved by introducing an inductor in the charging path.

Noise and thermal stability of vibrating micro-gyrometers preamplifiers [PDF]

open access: yes, 2007
The preamplifier is a critical component of gyrometer's electronics. Indeed the resolution of the sensor is limited by its signal to noise ratio, and the gyrometer's thermal stability is limited by its gain drift.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
