摘要

In this brief, an enhanced derivative superposition (DS) method is proposed to increase the third-order input intercept point (IIP3) of double-balanced CMOS active mixers. In the proposed mixer, an auxiliary common-gate transconductor biased in the moderate inversion region with a source inductive degeneration is used in the feedforward AC-coupled path to the main transconductor to generate the th...
