CMOS voltage reference with multiple outputs

open access: yesIET Circuits, Devices & Systems, 2008
A voltage reference with two outputs is presented. Both of them are insensitive to temperature, supply voltage and threshold voltage. One of the outputs is ∼0.8 V, and the other one is ∼0.38 V. For the output voltage of 0.8 V, this voltage variation because of supply voltage change from 2.0 to 3.5 V is ±0.66%, and because of temperature change from 0 ...

MOSFET analog memory circuit achieves long duration signal storage [PDF]

open access: yes, 1966
Memory circuit maintains the signal voltage at the output of an analog signal amplifier when the input signal is interrupted or removed. The circuit uses MOSFET /Metal Oxide Semiconductor Field Effect Transistor/ devices as voltage-controlled switches ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Consensus control of multiple electric springs considering non-critical load electricity fairness in islanded microgrid

open access: yesInternational Journal of Electrical Power & Energy Systems
Due to the uncertainty of renewable energy source (RES) generation, the islanded microgrid with RESs is prone to voltage and frequency fluctuations. The electric spring (ES) is an effective means to mitigate these fluctuations.

A nonvolatile analog programmable voltage source using the VIPMOS EEPROM structure [PDF]

open access: yes, 1993
A programmable voltage source using the vertical injection punchthrough based MOS (VIPMOS) EEPROM structure is presented. The circuit operates at a single 5-V supply and the output voltage is continuously available even during programming.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Implementation Joule Thief Buck-Boost Converter in A Neodymium Wind Power Plant

open access: yesInternational Transactions on Electrical Engineering and Computer Science
Wind power generation is gaining popularity as an environmentally friendly renewable energy source. However, the output voltage of a wind generator usually varies according to the wind speed, requiring a power converter to produce a stable DC voltage ...

Phase detector for three-phase power factor controller [PDF]

open access: yes, 1984
A phase detector for the three phase power factor controller (PFC) is described. The phase detector for each phase includes an operational amplifier which senses the current phase angle for that phase by sensing the voltage across the phase thyristor ...
