*Question: Why low-power VLSI technology is preferred over VLSI technology?

Answer: Low power VLSI is preferred over VLSI  because of the following reasons: 

• It consumes less power i. e. the power consumption is low.

• The power dissipation is also low.

• Most of the modern devices need to operate at low-power.

• Complex systems can be designed with reliability as the power consumption is low.

We use modern electronic devices like mobiles and robotics are generally compact and movable. Hence, they operate with a battery rather than power-connection. Hence, we prefer low-power operation.
