As power consumption has become one of the most important metrics of CPU design, we've seen a variety of methods proposed for lowering CPU TDP. Intel makes extensive use of dynamic voltage and ...

1. Leakage becomes critical as designs approach subthrehold voltages around 0.3 V. Ambiq Micro’s Apollo family of ARM Cortex-M4F microcontrollers utilize a subthreshold voltage design that allows the ...

Engineers considermany forms ofcurrent leakagein electronicsystems tobe unusable.This thinkingis starting to change asdesigners begin to explorenew frontiers in ultra-low-powerdevices through ...

Researchers at the National Institute of Advanced Industrial Science and Technology have demonstrated the enhanced performance and high reliability of tunnel transistors (tunnel FETs), which are ...

When looking at new architectures for low-power operation, it is easy to get fixated on one part of the design and ignore the ramifications for the rest of the system. The consequences of that are ...

Back in 1999, Bob Pease touched on the operation of CMOS transistors in subthreshold mode. In his article, he pointed out that analog designers can use CMOS ICs such as the CD4007, a dual matched pair ...

The quest to achieve ever-lower operating voltage and lower power consumption levels in circuit design is a trend that has placed difficult challenges on electrical engineers as they run up against ...

The shaded area of 150 mV is the operating voltage range of the transistor, which is much narrower than the operating range of conventional silicon transistors (500mV). The subthreshold swing (slope ...
