Abstract :
An ultra-low voltage 32b RISC core is realized with an ultra-low-voltage CMOS technique. An operating frequency of 16MHz is attained with a supply voltage of 500mV and a frequency of 375kHz is attained with a supply voltage of 230mV. Compared to the state-of-the-art-operating from 250 to 500mV, this work offers 6.7× and 125× respective improvements in operating speed.
