Abstract

This paper introduces a Gilbert-type active CMOS mixer integrated in 0.18 um process. Radio frequency signals are feed to the input ports of mixer, and then down-converted to IF band of 1 MHz. No inductor is employed in this circuit to reduce the circuit size. The circuit requires a 1.8 V voltage source and consumes only 3.3 mW when in normal mode. With gain increasing strategy, simulation results indicate the active mixer has a conversion gain of 6.2 dB, IIP3 of -4.4 dBm, noise figure of 12.8 dB.It is suitable for low-power frequency translation applications.
