Abstract
Official abstract text for this publication.
Apparatus and methods are disclosed related to low-voltage radio transmitters with high spectral purity. One such apparatus includes a baseband path with a predistortion stage, a programmable filter, and an upconverter core. In an embodiment, the programmable filter is placed between the predistortion stage and the upconverter core. In an embodiment, the programmable filter is configured by a controller to reject out-of-band noise introduced at the predistortion stage or earlier.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of processing a signal comprising: predistorting an analog signal to generate a predistorted signal, wherein the predistorted signal at least partially compensates for non-linearity of a transistor; filtering the predistorted signal to generate a filtered signal; and upconverting the filtered signal, wherein the transistor to be compensated is used in upconverting, wherein predistorting comprises operating a replica transistor in a feedback l…
