Abstract
An oscillator arrangement for time-to-digital converters for a 3D image sensor device includes a plurality of oscillators arranged as an array each oscillator being associated to one time-to-digital converter, and at least one coupling unit respectively arranged between at least two of the oscillators, so that oscillation in the at least two oscillators at a fundamental frequency is synchronized between the at least two coupled oscillators.
