A linearity improvement technique for elliptic filters in low-supply-voltage transceiver design for 5G (5th generation of mobile technology) communication systems has been proposed. The zero in the transfer function has been placed at the third-harmonic of the intermediate frequency (IF) signals in order to suppress the undesirable components, and thus the total harmonic distortion (THD) can be dramatically reduced. To achieve precise zero control to maximize linearity optimization, the… CONTINUE READING
