Abstract
A technique for on-chip time measurement includes dynamically scaling a range of a time-based digital-to-analog converter to enhance resolution of the time measurement. An apparatus includes a first time-based digital-to-analog converter configured to generate a first clock signal based on a first reference clock signal and a first digital code. The apparatus includes a second time-based digital-to-analog converter configured to generate a second clock signal based on a second reference clock signal and a second digital code. The first reference clock signal has a first frequency and the second reference clock signal has a second frequency that is harmonically related to the first frequency. The apparatus includes a time signal converter configured to generate an output signal having a level indicative of a time-of-arrival of a first edge of the first clock signal relative to a time-of-arrival of a second edge of the second clock signal.
