摘要
提出了一种适用于多波段收发器的新型宽带压控振荡器(VCO)。所提出的压控振荡器具有一个核心压控振荡器和一个调谐范围扩展电路，该电路由开关、混频器、分频器和具有抑制杂散技术的可变增益合成器组成。实验结果表明，采用0.18 μ m CMOS工艺制备的fmt具有-206dBc/Hz的0.98 ~ 6.6 GHz连续调谐频率。频率调谐范围(FTR)为149%，芯片面积为800 μ m × 540 μ m。
A 0.98 to 6.6 Hz Tunable Wideband VCO in a 180nm CMOS Technology for Reconfigurable Radio Transceiver
This paper proposes a novel wideband voltage-controlled oscillator (VCO) for multi-band transceivers. The proposed VCO has a core VCO and a tuning-range extension circuit, which consists of switches, a mixer, dividers, and variable gain combiners with a spurious rejection technique. The experimental results exhibit 0.98-to-6.6 GHz continuous frequency tuning with -206dBc/Hz of FoMT, which is fabricated by using a 0.18 mum CMOS process. The frequency tuning range (FTR) is 149 %, and the chip area is 800 mum x 540 mum.
