Abstract

This paper describes a RF Down-Conversion Mixer for mobile communication systems. This circuit achieves low voltage operation and low power consumption by reducing stacked devices of conventional gilbert cell mixer. In order to reduce stacked devices, we use source-follower structure. The proposed RF Down-Conversion mixer operates up to 1.85GHz at 1.5V power supply with 0.25um CMOS technology and consumes 2.2mA.
