An Improved CMOS GHz-range Gilbert Mixer

  • Hamid Reza Sadr Manouchehri Naeini Islamic Azad University, Damavand branch

Abstract

In this paper, a new topology of Gilbert mixer with improved power consumption using the CMOS 0.18μm TSMC RF design kit is proposed.  The proposed mixer is a down conversion one working in 2.4GHzradio frequency (RF), with a 2.5GHz local oscillator (LO) and a 100MHz intermediate frequency (IF).  The circuit of this mixer is based on a low power differential transconductor in RF stage, wherein the ac and dc current paths through the source degeneration resistors and dc bias are isolated from each other.  The supply is 1.8Vdc and the obtained power consumption is as low as 1mW.
