A novel high gain and low noise figure CMOS mixer with fully integrated esd protection

Abstract

A creative method to reduce the voltage head room requirement in the design of double balanced mixer is introduced. Design of a novel high gain, low noise figure and low power CMOS mixer with fully integrated ESD protection is presented. The mixer was implemented in ST 90nm CMOS technology and was packed in a QFN package. With an operating frequency of 1.575 GHz this mixer was targeted for GPS front-end receiver application.
