Ultra-Low-Voltage Electrowetting
The Journal of Physical Chemistry C, 2010Electrovariable optical components based on liquid/liquid interfaces encompass microfluidic lenses and mirrors, fiber-optic switches, and display elements. These devices function on the basis of the electrowetting effect, where a liquid interface is deformed by an applied electric field. Existing electrovariable lenses use electrowetting on dielectrics;

Journal of Circuits, Systems and Computers, 1995
This paper summarizes some of the current solutions to fulfil the requirements of the new low voltage power systems. On one hand, microelectronics evolution demands lower supply voltage. On the other hand, the portability of the new communication systems demands lighter and smaller power electronics.

A low voltage low output impedance CMOS bandgap voltage reference
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013A low voltage bandgap architecture is proposed. The opamp in the proposed bandgap is used for both generating the output reference voltage (Vref) and achieving low output impedance. To allow Vref to have different values within the supply voltage limits, a transconductor is proposed and used in conjunction with the opamp to supply the biasing currents ...

A low voltage CMOS low drop-out voltage regulator
SPIE Proceedings, 2009A low voltage implementation of a CMOS Low Drop-Out voltage regulator (LDO) is presented. The requirement of low voltage devices is crucial for portable devices that require extensive computations in a low power environment. The LDO is implemented in 90nm generic CMOS technology. It generates a fixed 0.8V from a 2.5V supply which on discharging goes

FLUORESCENT lamps have been developed, simple in design, and operating through suitable ballast from 115- and 230-volt a-c circuits. They are tubular in form, and the fluorescent material is energized by a hot-cathode positive-column electric discharge.

Low Voltage Analogue Multiplier
APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006With the reduction in supply voltages in order to minimize power dissipation, arises the need for a low voltage analogue multiplier. Developed is a multiplier that operates at as low a voltage as that required to bias a single n-MOS transistor by utilizing CMOS, as against the conventional multipliers which use either n-MOS or p-MOS transistor in the ...

Pediatrics, 1971
The hazards accompanying the increasing use of line-operated electrical devices for diagnosis and therapy as well as the more common hospital appliances such as electrically operated beds, television sets, radio sets, and so forth have been recently reemphasized.1 Most physicians are aware of the dangers of alternating current (60 Hz AC) or of high ...

Low-voltage arc sustainability
2017 IEEE IAS Electrical Safety Workshop (ESW), 2017Arc Flash in low voltage equipment (480 volts and below) is a safety issue that can impact work practices for electrical workers. When estimating incident energy for low voltage equipment, the duration of the arc is typically the driving factor. This paper summarizes previous testing results that establish arc sustainability for various equipment ...

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1995
This paper reviews the design of analog filters at low supply voltage. In particular, the main focus is on switched capacitor and g/sub m/-C type filters because, at the present time, they have the greatest commercial importance. SC implementations are discussed in the context of low frequency high precision applications while g/sub m/-C ...

2006 IEEE International Symposium on Circuits and Systems, 2006
This paper presents a low-ripple voltage tripler charge-pump intended to provide a stable supply voltage to the cascaded circuits, thus allowing relaxed design specifications of the latter. The structure, which is implemented by means of an array of charge pump modules sequentially enabled, was developed for a phase-change memory (PCM) device, but it ...
