Abstract
Apparatus and methods are provided relating to time-to-digital based analog-to-digital converter. An apparatus includes a time-to-digital converter based analog-to-digital converter for generating a first signal and a second signal having a timing relationship between a rising edge of the first signal and a rising edge of the second signal based on a sampled input analog voltage level, and converting the timing relationship into a corresponding time-to-digital representation. The time-to-digital representation is obtained without any voltage comparison and current comparison.
