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 ...

Low-voltage differential amplifier
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009A low-voltage differential amplifier constructed by bulk-driven PMOS transistors is proposed in this paper. A local positive feedback is utilized that boosts the input transconductance and improve the noise performance. The input common-mode range is also compared to the gate-driven counterpart.

Low voltage fault attacks to AES
2010 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST), 2010This paper presents a new fault based attack on the Advanced Encryption Standard (AES) with any key length, together with its practical validation through the use of low voltage induced faults. The CPU running the attacked algorithm is the ARM926EJ-S: a 32-bit processor widely deployed in computer peripherals, telecommunication appliances and low power

Proceedings of the 2009 ACM/IEEE international symposium on Low power electronics and design, 2009
Power dissipation is one of the major design concerns for nano-scale CMOS systems. In this talk I will first present ultra low voltage design challenges for both logic and memory considering different levels of design abstraction — device, circuit, and architecture.

LOW VOLTAGE IN THE ELECTROCARDIOGRAM
Archives of Internal Medicine, 1932In the course of the routine interpretation of electrocardiograms, records are frequently encountered in which the Q-R-S complexes are small. The condition is called "low voltage" when the greatest excursion is less than 5 mm. in amplitude in all three leads. 1 It is not uncommon.
