چکیده
A highly linear down conversion mixer with moderate gain used for 2.4GHz RF applications is presented in this paper using 0.18μm CMOS technology. The proposed mixer incorporates current bleeding technique & degenerative resistors to improve linearity and conversion gain. Also the negative feedback configuration of the circuit gives flat conversion gain increasing the overall bandwidth. The simulation results reveal that the proposed mixer shows input referred third order input intercept point (IIP3) at 13.13dBm, 1dB compression point at -9.94dBm with conversion gain of 9dB. The circuits operates at 1.8V power supply and dissipates 9mW power. Keywords—Conversion gain, Gilbert Cell, IIP3, Linearity, Mixer, RF CMOS. ©KY PUBLICATIONS SHIVEN PANDYA
