Title
Highly Linear Common-Gate Mixer Employing Intrinsic Second And Third Order Distortion Cancellation
Abstract
This paper presents a new derivative superposition scheme for simultaneous cancellation of second and third-order distortions in common-gate transconductance stage of mixer, addressing the challenging dynamic range required in multi-mode front-end CMOS circuits. Using Volterra series analysis, the unsatisfactory results of conventional derivative superposition in common-gate structures, and thus the need for simultaneous cancellation is investigated. An inductor interposed between two transconductances tunes out the parasitic capacitors and improves conversion gain. Simulation results of proposed mixer in a 0.13 mu m-CMOS technology with 1.2V supply illustrate 16-dB improvement in IIP3 and 30-dB increase in IIP2 compared to conventional Gilbert mixer.
