IJCAES A 2 . 4 GHz Op-Amp Based Up-Conversion Mixer for Zigbee Front-end Transmitter

This paper illustrates up-conversion mixer with very high linearity and improved conversion gain. CMOS Operational amplifier is used to enhance the overall conversion gain of the proposed mixer circuit. The derivative Superposition technique is applied to improve the linearity of the proposed Up-conversion mixer circuit. The operating frequency of this… CONTINUE READING
