| 摘要 | 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. | ||

| 主权项 | 1. A method for turning off a subset of amplifier segments in a set of turned on amplifier segments arranged in an integrated circuit so that a distance is established between any two adjacent turned on amplifier segments in the set of turned on amplifier segments 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. | ||
