摘要:A quadrature phase-shift keying (QPSK) demodulator frontend for a passive optical network (PON) optical network unit receiver fabricated in CMOS 0.13-mu m technology is presented. The frontend integrates a compact 5-GHz ring quadrature voltage-controlled oscillator (QVCO), two inductor-less broadband mixers, and two second-order LC ladder low-pass filters. The broadband mixers operate with an input frequency between 2.5 and 7.5 GHz and with an input 1-dB compression point of -5 dBm. Area-saving design techniques are applied to lower the cost of the terminal receivers, because a competitive cos
