Abstract The design of a low‐voltage low‐power wideband mixer for radio‐frequency applications is presented in this Letter. Two different input‐matching topologies are employed to see the effects of the matching on the mixer's wideband performance. The new strategy of midway matching is proven to be satisfactory for the wideband applications. Simulations are based on a 0.25‐μm CMOS process. A simulated SSB noise figure of 10.3 dB, a conversion gain of 9.4 dB, and a power consumption of 8.3 mW are among the main achievements. © 2002 Wiley Periodicals, Inc.
