这份报纸论述充分综合的低噪音多乐队 LC 坦克 voltage-controlled-oscillator (VCO ) 的设计和实现。多乐队操作被使用开关电容器共鸣器完成。另外的三小点的二进制加权的电容器数组也被用来扩大在每个乐队调节范围的频率。到更低的阶段噪音,二个噪音过滤器被增加,一个线性可变电抗器被采用。在 0.18 m complementary-metal-oxide-semiconductor (互补金属氧化物半导体) 实现了进程,当时, VCO 完成调节盖住 2.262.48 GHz, 2.482.78 GHz, 2.943.38 GHz,和 3.454.23 GHz 的范围的频率占据 0.52 mm2 的一个芯片区域。与 1.8 V 电源供应,它分别地从最低乐队拉 10.9 妈, 10.6 妈, 8.8 妈,和 6.2 妈的电流到最高级的乐队。测量阶段噪音分别地来自搬运人在 1 MHz 和 2.5 MHz 偏移量是 109120 dBc/Hz 和 121131 dBc/Hz。
This paper presents the design and implementation of a fully integrated low noise multi-band LC-tank voltage-controlled-oscillator (VCO). Multi-band operation is achieved by using switched-capacitor resonator. Additional three-bit binary weighted capacitor array is also used to extend frequency tuning range in each band. To lower phase noise, two noise filters are added and a linear varactor is adopted. Implemented in a 0.18 ~tm complementary-metal- oxide-semiconductor (CMOS) process, the VCO achieves a frequency tuning range covering 2.26-2.48 GHz, 2.48- 2.78 GHz, 2.94-3.38 GHz, and 3.45-4.23 GHz while occupies a chip area of 0.52 mm2. With a 1.8 V power supply, it draws a current of 10.9 mA, 10.6 mA, 8.8 mA, and 6.2 mA from the lowest band to the highest band respectively. The measured phase noise is - 109-- 120 dBc/Hz and - 121-- 131 dBc/Hz at a 1 MHz and 2.5 MHz offset from the carrier, respectively.
