摘要

延迟元件中的本地正反馈使只有两个阶段的环形振荡器振荡并产生正交时钟。劳斯-赫维茨准则被用来证明这种结构可以振荡。内部产生的电源从恒定的偏置保持自由运行频率在±5%，从-40到125°c的过程变化。0.13 μ m CMOS的1.25 GHz振荡器消耗3.4 mA，在1MHz偏移时相位噪声为-88 dBc/Hz。

A Process and Temperature Compensated Two-Stage Ring Oscillator

Local positive feedback in a delay element enables a ring oscillator with only two stages to oscillate and produce quadrature clocks. Routh-Hurwitz's criterion is applied to prove that such a structure can oscillate. An internally generated power supply from a constant-gm bias keeps the free running frequency to within plusmn 5% from -40 to 125degC over process variations. The 1.25 GHz oscillator in 0.13 mum CMOS draws 3.4 mA and has a phase noise of -88 dBc/Hz at 1MHz offset.
