Abstract | N-path passive-mixer-first receivers suffer from a tight tradeoff between noise figure (NF), linearity and power due to no RF gain. This paper describes an extensively-current-reuse wideband receiver exploiting parallel N-path active/passive mixers. The key features are: 1) a stacked RF-to-BB front-end with an 8-path active mixer realizing RF amplification, harmonic-recombination (HR) downconversion 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 low-pass 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 third and fifth harmonic rejection ratios (HRR 3,5) with low hardware intricacy. Measurements over the TV bands (0.15 to 0.85 GHz) manifest favorable NF (4.6 \pm 0.9 dB) and out-of-band IIP2/IIP3 (+61/+17.4 dBm) at small power (10.6 to 16.2 mW) and area (0.55 mm 2). The HRR 2-6 are > 51 dB without any calibration or tuning. The ultimate out-of-band P-1dB is > +2.5 dBm. The BB stopband rejection is > 86 dB at 150 MHz offset. |
