Abstract :
This paper presents a topology for Gilbert-cell mixer that leads to a better performance in terms of noise figure, conversion gain and IIP3 at low supply voltage. In this architecture, we have used an extra LC filter for reduction parasitic capacitance noise in switching. Simulation results show the voltage CG of 17.45 dB, NF of 7.04 dB, and IIP3 of -4 dBm.
