Frequency translation in a system is performed by a non-linear device known as a mixer. A substantial discussion has been provided for several CMOS circuit configurations which are currently used to realize a frequency mixing operation with more emphasis on their working and operation as a mixer. Three topologies, single balanced mixer, double balanced mixer and double balanced dual gate mixer are presented here using 45nm VLSI technology. The mixer is designed in Cadence Virtuoso tool version 6.4.1. The three topologies are compared on the bases of average DC power consumption and port-to-port isolation.
