The TFA consists of 16 Transistors and dissipates less power than conventional CMOS full adders.
The analysis has showed that the one-bit full adders without driving capability (TG and LP) are the fastest, and have power dissipation quite low; hence, they are suitable for low-power adders, even though their advantage strongly decreases reducing the power supply.
The 16 T full adders do not show good power consumption.

The use of 16 transistors full adder shows good efficiency.
For 32nm MOSFET technology array multiplier with 10T full adder is used.
