    摘要

    A CMOS mixer was design with a new circuit scheme to realize low voltage and high linearity simultaneously. A double balanced Gilbert cell was adopted as the basic topology and TSMC 0.18μm 1P6M CMOS process was employed for the on-chip RF circuit fabrication. The proposed new circuit scheme consists of LC-tanks as a capacitively coupled resonator for low voltage and multi-stage parallel RC networks for linearity improvement. Furthermore, multi-gated structure is applied at the RF input as a transconductance amplifier to enhance conversion gain and linearity. The new circuit scheme enables a successful low voltage operation at 1-V for 0.18|a.m technology. The measured circuit performance demonstrates superior linearity with IIP3 of 11 dBm and PldB of 2.2 dBm. The conversion gain can be maintained at 8.1 dB in a wide frequencies of 5GHz to 6.8GHz.
