Abstract
The present subject matter is directed to a high-speed high resolution and accuracy time interpolator circuit. The interpolator uses basic dual ramp time-to-digital converter architecture, but provides circuits and methodologies to improve the accuracy, reduce the effective intrinsic jitter, and reduce the measurement time. Improved aspects of the present subject matter correspond to the introduction of a current mirror for improved settling time, a high frequency clock for improved resolution and ADC sample processing to improve resolution and accuracy.
