Abstract

We present a low-power high-linearity capacitive harmonic rejection mixer for cognitive radio applications. A passive mixer first receiver with capacitive 16-phase sinusoidal weighting implements harmonic rejection down-conversion, and an AC-coupled fully differential capacitor feedback transimpedance amplifier provides baseband linear voltage gain and band-pass filtering achieving an in-band IIP3 of +12.5 dBm at 320 MHz LO over 3 MHz baseband. The 1.62mm2 mixer in 65nm CMOS consumes 40 μW per I/Q complex output channel, and 7.82 mW for 16-phase PLL clock generation and distribution.
