In this article, a new CMOS low voltage low power high‐linearity current‐reuse current‐mirror‐switch (CR‐CMS) mixer based on chartered 0.18‐µm CMOS technology for 2.4‐GHz IEEE 802.11b WLAN receiver applications is presented. The new CR‐CMS technical is proposed and used in the mixer, which makes the mixer different from the traditional Gilbert mixer. Because of the new CR‐CMS technique used in the mixer, the postlayout simulation results demonstrate that the CR‐CMS mixer can provide about 8.5‐dB conversion gain with a local oscillator power of −5 dBm, while the power consumption is only 1.16 mW with a 1 V supply voltage, and the input‐referred third‐order intercept point of the mixer is 16.3482 dBm. The chip area including test pads is only 0.33 × 0.44 mm 2 . Comparing with the previously reported CMOS mixers, the proposed CR‐CMS mixer has the advantages of lower supply voltage, lower power consumption, higher linearity, and smaller chip area than most of the other reported work. © 2013 Wiley Periodicals, Inc.
