Abstract
In one embodiment, the present invention includes an apparatus having at least two gain stages to receive incoming signals and to output amplified signals, along with multiple regulators. More specifically, a linear regulator can be coupled to the first gain stage to provide a first regulated voltage to the first gain stage, and a switching regulator coupled to the second gain stage to provide a second regulated voltage to the second gain stage.
