Abstract
A timing generator contains an oscillator section (10) formed with a plural number of stages (S.sub.1 -S.sub.N) for respectively producing a like number of stage signals (V.sub.S1 -V.sub.SN) that sequentially change signal values at a basic oscillator frequency (f.sub.O). 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 (V.sub.T1 -V.sub.TM), 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 (f.sub.R) to have a substantially fixed relationship.
