Abstract
A novel time-to-amplitude converter (TAC) topology is presented that allows the conversion of time durations down to and including zero. The stability of this circuit depends only on the matching of two DC current sources. Over a 16 ns full-scale range the integral nonlinearity of this circuit was <+or-0.15%; the differential nonlinearity was <+or-2% over the top half of the range and <+or-6% over the bottom half of the range.<>
