A Novel 2.4GHz CMOS Up-Conversion Current-Mode Mixer
Recently, the growing demand for RF and wireless applications has attracted a great deal of researches on designing high performance and low cost RF integrated circuits and systems with the advanced CMOS technologies. In the RF transmitter front-end, one of the indispensable analog blocks is the up-conversion mixer. The purpose of an up-conversion mixer is to convert the incoming Intermediate Frequency (IF) signal to a radio frequency component for reliable transmission. The structure of up-conversion mixer has been reported in many CMOS designs.
