Description
Summary:This paper investigates a current-reuse bleeding double-balanced mixer operating at 5.26 GHz together with the issues of design and implementation. The up-conversion mixer is configured with the structure of Gilbert Cell and takes advantage of current-reuse bleeding. The up-conversion mixer uses an intermediate frequency (IF) input frequency of 10 MHz, a local oscillator (LO) frequency of 5.25 GHz, and an RF output frequency of 5.26 GHz. An experimental test chip is realized to compare with the conventional CMOS up-conversion mixer. From the measured results, the mixer demonstrates 6.5 dB conversion gain, and -9 dBm input IP3 with 15.3 mW power dissipation from a 1.8 V supply.
