Abstract :
In this paper, we have investigated several mixer structures including single-ended, single-balanced and double-balanced RF down-conversion mixers in 0.25 μm standard CMOS technology. The comparison of designed mixers with the recent literature shows significant improvement in some of the major performance parameters. The final differential double-balanced current-switching mixer shows a conversion gain of 6.1 dB, simulated noise figure of 8.3 dB and input 1-dB compression point of -8.3 dBm, consuming 5.6 mW at 2.4 GHz input RF and 250 MHz output IF frequency.
