Ultralow-voltage MTCMOS/SOI circuits for batteryless wireless system

Ultralow-power multi-threshold (MT) CMOS/SOI circuit technology, which makes it possible to lower the supply voltage of LSIs to 0.5 V and reduce power dissipation to the 1-mW level, provides self-powered batteryless operation for short-range wireless system. We overview MTCMOS/SOI circuit technology and describe some batteryless wireless systems built using MTCMOS/SOI LSIs.
