Ex-MIT company rethinks power-feasting amplifiers

—Technologists generally agree that power amplifiers have proven to be inefficient pieces of hardware. Turning electricity into radio signals, they eat into the battery life of smartphones and they waste power. One may find that a cellular phone cannot stream live video without running down the battery in minutes. Now a team of engineers have come up with an alternative amplifier technology that can extend smartphone battery life.

The result...
