Rather it continues showing an exponential behavior with respect to the subthreshold gate voltage.
[4][5] For a technology generation with threshold voltage of 0.2 V, subthreshold conduction, along with other leakage modes, can account for 50% of total power consumption.
[6][7] Some devices exploit sub-threshold conduction to process data without fully turning on or off.
Even in standard transistors a small amount of current leaks even when they are technically switched off.
Some sub-threshold devices have been able to operate with between 1 and 0.1 percent of the power of standard chips.
