Abstract | A single-ended-input current-reuse wideband receiver comprising (1) a stacked Radio Frequency to Baseband (RF-to-BB) front-end with an 8-path active mixer realizing RF amplification, harmonic-recombination (HR) down-conversion, and BB filtering in the current domain for better linearity and power efficiency; (2) a feedforward 8-path passive mixer enabling LO-defined input impedance matching without external components, while offering frequency-translated bandpass filtering and noise cancelling; (3) a single-MOS pole-zero lowpass filter (LPF) permitting both RF and BB filtering at low voltage headroom consumption, while easing the tradeoff between the in-/out-of-band linearity; and (4) a BB-only two-stage HR amplifier boosting the 3rd and 5th harmonic rejection ratios (HRR3, 5) with low hardware intricacy. |
