Abstract

This paper presents an improved circuit of active CMOS based Gilbert double balanced differential mixer used in Bluetooth and Zigbee receiver systems. Proposed mixer design technique is aimed to achieve high conversion gain and linearity with low power consumption. Modified resistive source degeneration technique is used for the linearity improvement and active load with resonator circuit is used to enhance the conversion gain of the mixer. The range of RF frequency is 2.4GHz to 2.48 GHz and intermediate frequency (IF) varies from 1MHz to 2MHz. The Input Third Order Intercept point (IIP3) provided by the circuit is -7.311dBm at 2.48 GHz RF frequency. The conversion gain provided by the proposed mixer is 10.737. The circuit is implemented using 0.18μm CMOS process using 2.2V supply.
