Power Valve: for low power operation and low stand-by power
The concept of Power Valve is presented. It consists of power switch transistors and control circuits, which give variable impedance to the power supply. The circuit controls the internal power supply voltage of logic circuits and reduces the voltage swing of signals. An experiment using a 130-nm test chip showed a 36.0% operating power reduction for a

Ultralow-Power SOTB CMOS Technology Operating Down to 0.4 V
Ultralow-voltage (ULV) CMOS will be a core building block of highly energy efficient electronics. Although the operation at the minimum energy point (MEP) is effective for ULP CMOS circuits, its slow operation speed often means that it is not used in ...

Review on Coupled Thermo-Hydraulic Performance of Nanofluids and Microchannels
As electronic components continue to be miniaturized, the heat flux density continues to increase. Scholars have proposed the use of microchannel heat sinks (MCHS) to dissipate heat from devices with high heat flux density, and have pointed out that the ...

Low Power Contactless Voltage Sensor for Low Voltage Power Systems [PDF]
Contactless measurements represent the desirable solution in many contexts, where minimal cabling is required or, in general, cabling is not possible. This paper presents a new contactless voltage sensor for low voltage power systems. It is based on a contactless capacitive probe, which surrounds the power cable.
