摘要: This study demonstrates a wide frequency tuning range LC voltage-controlled oscillator (LC-VCO) with an active inductor in a 90-nm CMOS process. As the proposed LC-VCO is intended to be extremely flexible without redesign for several new-generation SerDes interfaces, a wide operating frequency makes the phase-locked loop (PLL) applicable to the multistandards. To demonstrate a highly competitive design, a quality (Q) factor enhancement technique has been also demonstrated to reduce the loss from the active inductor, leading to an appropriate phase noise over the entire tuning range. At a supply of 1.2 V, the fabricated LC-VCO provides a frequency tuning range of 0.9-8 GHz (160%) with power consumption of 3.2-19.1 mW. The measured phase noise is from -105 to -118 dBc/Hz at a 1-MHz offset. Realized in a fully integrated PLL chip, it occupies an active area of 0.08 × 0.16 mm 2 . 其他題名: TCSII 出版者: New York: IEEE 出版日期: 2014-08 出處: IEEE transactions on circuits and systems.
