Abstract
A system and method are provided for converting voltage-to-time-to-digital signals. The method periodically samples a continuous analog input and discharges the sampled analog input at a predetermined rate to supply a continuous analog ramp signal. The ramp signal is converted into an n-bit coded digital word representing the q most significant bits (MSBs) of a k-bit binary word, where q is an integer greater than 0, n is an integer greater than 1, and k is an integer greater than q. At least one bit of the coded digital word is supplied at a time representing the p least significant bits (LSBs) of the k-bit binary word. The coded digital word is converted into a single-bit pulse signal containing timing information representing the p LSBs of the k-bit binary word at an output, and the timing information is converted into the p LSBs of the k-bit binary word.
