| Popis: | In this paper we present a wideband harmonic rejection (HR) RF receiver design. Both gain mismatch and phase mismatch of the HR mixer have been calibrated using a design and calibration method called extended statistical element selection to achieve best-in-class HR ratio (HRR) performance. The achieved concurrent 3rd order HRR and 5th order HRR are greater than 80dB and 70dB, respectively, after calibration. The even order HRR is also calibrated to greater than 80dB. A single calibration performed at 750MHz was further observed to be effective over more than two octaves of bandwidth with greater than 70dB HRR. The receiver was manufactured in 65nm CMOS technology. Input RF frequency range was 0.15-1GHz and the receiver consumes 64mW at 1GHz. Noise figure is 3.2dB and out-of-band IIP3 is -7dBm at a total gain of 48dB. A wideband RF receiver with best-in-class harmonic rejection performance is presented.A novel design method is proposed for high calibration resolution and wide calibration range.Harmonic rejection calibration performed at one frequency is effective at a wide frequency range. |
