Abstract

This paper proposed a full band up-mixer implemented in 0.18μm COMS process for UWB wireless systems. The linearity, noise figure and other performance are improved by using current bleeding technique and inserting a LC network on common source nodes of the switches stage. The inductance peaking technique is adopted to flatten conversion gain over the 14 sub-bands of UWB system. The up-converting mixer converts an input of 264MHz intermediate frequency to an output of 3.1---10.6GHz radio frequency signal. From the post simulation results, the proposed up-mixer achieves conversion gain of 10卤1dB and the IIP3 of 7.19dBm and power consumption of 2.4mW at 1.2V power supply.
