Abstract
A generator includes an oscillator for producing a clock signal from N logic signals representing an N-bit control number, with N being an integer greater than 1. The oscillator has N+1 components. The N most significant components are each assigned a place value i ranging from 1 to N, and a least significant component provides the clock signal. At least one component with a place value i greater than 1 includes first and second arms. The first arm includes a cell and a first switch connected in series, and the second arm includes 1+2 cells and a second switch connected in series. Each cell includes an odd number of inverters.
