Abstract
A time to digital converter with a successive approximation architecture () and a method thereof is provided. The time to digital converter () includes successive approximation analog to digital converter circuitry () configured for converting the differential voltage established in the digital to analog converter () of the successive approximation analog to digital converter circuitry () to a digital representation thereof, where the differential voltage corresponds to a measured time period representing a time difference between receipt of leading edges of two signals. Time to digital converter () may incorporate a current switching unit (') having a plurality of current switching circuits (--) arranged in parallel to increase the precision of digital time output of time to digital converter (). The plurality of current switching circuits (--) can be selectively enabled to alter the sensitivity of the time to digital converter ().
