摘要：

This letter presents a wideband mixer using a commercial 0.18-mu m CMOS technology process for ultra-wideband (UWB) system applications. To achieve wideband frequency response and low dc power consumption for UWB system applications, the folded approach is utilized to reduce supply voltage as well as dc power consumption, and wideband input matching network is used to achieve wideband frequency response. The measured results show that the proposed mixer demonstrates a wideband frequency response from 0.2 to 16 GHz with a: conversion gain of better than 5.3 dB. The dc power consumption is 15 mW under a supply voltage of 1.8 V, with a compact size of 0.68 mm x 0.65 mm.
