    • A timing generator contains an oscillator section (10) formed with a plural number of stages (S1-SN) for respectively producing a like number of stage signals (VS1-VSN) that sequentially change signal values at a basic oscillator frequency (f0). The oscillator section is typically implemented as a ring oscillator. In response to the stage signals, a timing-signal generating section (14) generates one or more timing signals (VT1-VTM), each having at least two transitions corresponding to transitions of two or more of the stage signals. A control section (12), preferably arranged in a phase-locked loop; causes the oscillator frequency and a reference frequency (fR) to have a substantially fixed relationship.
    • 定时发生器包括形成有多个级(S1-SN)的振荡器部分(10),用于分别产生以基本振荡器频率(f0)顺序改变信号值的相同数量的级信号(VS1-VSN)。 振荡器部分通常被实现为环形振荡器。 响应于级信号,定时信号产生部分(14)产生一个或多个定时信号(VT1-VTM),每个定时信号具有对应于两个或更多个级信号的转变的至少两个转变。 控制部分(12),优选地布置在锁相环中; 使振荡器频率和参考频率(fR)具有基本上固定的关系。
