What is the advantage of a 10 times lower operation voltage?
The power dissipation may be as much as 100 times smaller than the standard MOSFET! This follows from the ten times lower voltage and from the freshman physics formula for power P, which is: P = V2/R , where R depends on a number of parameters in an IC and must be defined as an effective resistance. If this much lower power consumption of a MOSFET can be extended to the same margin of advantage in a complex IC, then your laptop computer might operate 200 hours without charging the batteries instead of going dead after two hours. Furthermore, your cell phone might stay active for months without charging. Again, a very important result. Finally, the speed of operation may be as much as 10 times faster, since it takes much less time to apply (and remove) 0.2 V than it does 2.0 volts.
