Abstract
A multiphase comparator circuit includes a first differential stage; a first switching arrangement for connecting an output of the first differential stage to an input of a load circuit; and two or more regeneration stages. Each regeneration stage is connected to a load circuit and to the first switching arrangement. A clock-controlled second switching arrangement selectively provides an operating current to the regeneration stages. The first and second switching arrangements have switches that are driven so as to operate the regeneration stages in a manner temporally offset from each other.
