ABSTRACT:
An apparatus for improving linearity of small signal according to the present invention comprises a least of one non-linear signal generating means for receiving a first DC bias larger than a threshold voltage and for generating a non-linear signal; feedback means for returning the non-linear signal from said a least of one non-linear signal generating means; and amplifying means for receiving, amplifying and outputting to an output unit, a second DC bias larger than the threshold voltage and a reversed and feedback non-linear signal such that the non-linear signal is cancelled. The linearizers according to the present invention have a higher linearity and a simple constitution, and thereby being used for various terminals.
