Normally-off technologies for healthcare appliance
2014 19th Asia and South Pacific Design Automation Conference (ASP-DAC), 2014Battery mass and power consumption of wearable system must be reduced because the key factors affecting wearable system usability are miniaturization and weight reduction. This report describes a wearable biosignal monitoring system using normally-off technologies to minimize the power consumption.

Normally-off computing project: Challenges and opportunities
2014 19th Asia and South Pacific Design Automation Conference (ASP-DAC), 2014Normally-Off is a way of computing which aggressively powers off components of computer systems when they need not to operate. Simple power gating cannot fully take the chances of power reduction because volatile memories lose data when power is turned off. Recently, new non-volatile memories (NVMs) have appeared.

RRAM-based FPGA for "normally off, instantly on" applications
Proceedings of the 2012 IEEE/ACM International Symposium on Nanoscale Architectures, 2012"Normally off, instantly on" applications are becoming common in our environment. They range from healthcare to video surveillance. As the number of applications and their associated performance requirements grow rapidly, more and more powerful, flexible and power efficient computing units are necessary.

GaN HEMT devices: Experimental results on normally-on, normally-off and cascode configuration
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013Power electronics systems play key function in power management and motion control: power consumption and volume reduction are strongly required in new applications oriented to protect environment. Moreover, a switching frequency increase is demanded for microwave and power switching applications, thus reducing passive component and converter volume ...

Spin-RAM for Normally-Off Computer
2011 11th Annual Non-Volatile Memory Technology Symposium Proceeding, 2011Spin-RAM technologies for operation speed faster than 30 ns, memory capacity larger than 1 Gbits and practically infinite read/write endurance have been developed by using magnetic tunnel junctions with perpendicular magnetization layers. Combination of Spin-RAM and power-gating technology will enable ultra low power computer called Normally-Off ...

Threshold voltages of normally off MESFET's
IEEE Transactions on Electron Devices, 1972The threshold voltage of "normally off" Si-MESFET's for simple dc-coupled circuits is defined and computed with a two-dimensional device model, taking into account carrier velocity saturation and diffusion. The influence of the main parameters, gate length, conducting-layer thickness, and doping is investigated outside the range of Shockley's equations.

Normally-Off Mesfet Analogue Circuits
16th European Microwave Conference, 1986, 1986A very small (0.04 mm2) monolithic DC to 2GHz, input/output matched, amplifier using enhancement mode GaAs MESFET's has been realized, to demonstrate the analog circuits capability of this type of transistor. The gain of the amplifier is 12dB, its noise factor is 2dB.
