Abstract :
This paper presents design of analog mixer using modified Gilbert cell topology for use in RF front. The proposed circuit gives improvement in its performance. The input RF and LO frequency is set to 2500 MHz and 2250 MHz respectively, resulting in an output IF frequency of 250 MHz.The simulation results show that the conversion gain is 9.605 dB, single-sideband noise figure is 9.448 dB and output IM3 intercept point is 15.764 dBm with power consumption of 24.732 mW. It uses supply voltage of 1.8 V and the circuit layout has been obtained using CMOS 0.18 mum technology fabrication.
