Abstract

A single-ended input to differential output LNA with a cascode topology of the present invention overcomes a much greater consumption of current and area for the single-ended input to differential output LNA of the prior art. The LNA needs to supply an operating bias for each transistor. The LNA has a few transistors, a few capacitive impedances, and a few inductive impedances. The main objective of the present invention not only reduces costs and conserves area and current consumption, but also has a much higher linearity and gain under the same current consumption when compare to the prior art.
