Abstract

PURPOSE:To the next stage of PLL-MPX-IC is connected to low frequency amplifier circuit which produces IC distortion and adverse-phased distortion in order to offset and eliminate the distortion. As a result, feedback circuit or amplifier circuit can be deleted as well as the characteristics can be improved.
