Battery of smartphones and notebooks lasts longer "break through the theoretical limits of transistors", the power consumption goes to 1 / 10th or less

ByJames 4765

A new transistor has been developed that may greatly increase the battery duration of notebook PCs and smartphones. The power consumption of this transistor is less than 1 / 10th of the conventional power consumption, and the circuit area becomes 1/4, which means that you can expect a smartphone power up especially.

Katsuhiro Tomioka, a researcher at PRESTO, Japan Science and Technology Agency (JST), and Professor Takashi Fukui at the Graduate School of Information Science, Hokkaido University, succeeded in developing a new type transistor that is well below the theoretical limits of conventional transistors.

"Transistor" is a switching element that controls the flow of electrons with voltage and turns it on and off, and it is used as a fundamental part of semiconductor integrated circuits of personal computer LSI and microprocessor. Up to now, by increasing the integration degree by reducing this transistor, we have realized higher performance, lower power consumption and lower cost of semiconductor integrated circuits. However, leakage current leakage which is not used for the switch and leakage current of the transistorSubthreshold coefficientSince there is the theoretical limit (60 mV / digit) in the low power consumption, the power consumption has reached the limit, and the power consumption in the circuit has been increasing.

This time, teams such as Mr. Tomioka and Professor Fukui succeeded in suppressing current leakage. In addition, it achieved a value exceeding the theoretical limit of subthreshold coefficient of 21 mV / digit.

By realizing this technology, compared with present integrated circuits,The total power consumption can be reduced to 1 / 10th or lessIt will be like that. For batteries such as personal computers and smart phones, the duration is extended by reducing the power consumption of the circuit, and home appliances can significantly reduce standby power.
