Synthesis and design of a CMOS harmonic mixer with output power management for narrowband and wideband wireless communications: The bluetooth and UWB cases

The present chapter is about the synthesis and design of a passive mixer in CMOS technology with output power managment, which satisfies the demands established by Bluetooth and Ultra Wideband (UWB). The simulation in Mentor Graphicsr ICstudio 2008.2b of the harmonic mixer for the Bluetooth and UWB standards with the UMC 0.18μm Mixed Mode and RF CMOS technology have been carried out. The design for Bluetooth have a performance in Gc with -6.05dB, IIP3 of 15.5dBm, NF of 7.7dB and a variation of the conduction angle from 40%25 to 7%25. The proposed mixer works with the third harmonic of the LO source, this helps to reduce the frequency of the LO to reach the Bluetooth band. The second design is for the UWB standard, in the wich, the behavior of the proposed mixers for UWB have a performance in Gc with-6.63dB, IIP3 of 16.26dBm, NF 8.6dB, and a variation of the conduction angle from 28%25 to 7%25. The proposed mixer works with the fourth harmonic of the LO source, this helps to reduce the frequency of LO to reach the band UWB. © 2017 Nova Science Publishers, Inc.
