Abstract
Methods of turning on and/or turning off amplifier segments in a scalable periphery amplifier architecture are described in the present disclosure. The turning on and/or turning off the amplifier segments according to the various embodiments of the present can reduce spectral splatter in adjacent channels. In some embodiments, amplifier performance and efficiency can be improved by dissipating heat more uniformly.
Claims11
A method for turning off a subset of amplifier segments in a set of turned on amplifier segments arranged one by the other on a circuit, the method comprising:
- determining a number of amplifier segments to be turned off, thus determining the size of the subset of amplifier segments to be turned off;
- and
- turning off the amplifier segments of the subset of amplifier segments, wherein, upon the turning off, a post-turning off distance between at least two adjacent remaining turned on amplifier segments is greater than a pre-turning off distance between any adjacent turned on amplifier segments.
A method of turning on a subset of amplifier segments from a set of turned off amplifier segments arranged one by the other on a circuit, the method comprising:
- providing a plurality of amplifier segments in an amplifier circuit, wherein one or more amplifier segments of the plurality of amplifier segments are turned off according to a set sequence and a set arrangement;
- and
- turning on the amplifier segments in a substantially similar sequence and arrangement as the set sequence and the set arrangement.
