Abstract
A 5.25-GHz CMOS even harmonic mixer (EHM) using a dual class-AB circuit is presented. The dual class-AB circuit in the RF stage can improve the linearity and conversion gain for wireless receivers. In addition, the dual class-AB circuit adjusting the mixing power from the frequency-doubling circuit can overcome the process variation. After an implemented chip, the measurement reveals that the proposed EHM has a power consumption of 4.13-mW, conversion gain of 13.133-dB, IIP3 of -1.033-dBm, and IIP2 of 48.267-dBm under the LO frequency of 2.623-GHz. With a measured linearity upon a high power conversion gain, the proposed EHM shows improved performance compared with other published active EHMs.
