Abstract
An address generator for compensating non-linear distortion of a transmitting amplifier according to this invention comprises transmission power calculation means for calculating transmission power based on transmission data, a comparator control circuit, and an address generation table. The address generation table comprises a plurality of comparators operating in parallel. The comparator control circuit turns on only necessary comparators based on the transmission power value so as to reduce power consumption.
