Abstract
Principles of conversion of single time intervals into a digital code with the use of interpolation of the reference period for reducing the sampling error are reviewed. Interpolating converters are based on integrated digital delay lines and phase interpolation elements, which allow the resolution lower than the propagation delay of a single logical gate to be reached.
