Abstract
A mixer circuit is disclosed. The mixer circuit comprises a plurality of mixer elements, wherein there are non-overlapping clock signals provided to the plurality of mixer elements which have a duty cycle of 33⅓ percent. Outputs signals of the mixer elements do not contain third order harmonic content of the non-overlapping clock signals. The third-order harmonic of the mixer is eliminated by using mixer which uses voltage sampling on non-overlapping clocks and thereby achieves high linearity. The mixer circuit is further expanded to remove the I-Q image and even order harmonics.
