摘要
The present invention is directed to a comparator circuit for use with in-phase and quadrature phase signals and a method of comparing a resultant vector of the in-phase and quadrature phase signals. In one embodiment, the comparator circuit includes a non-titled comparison circuit that compares a resultant vector of the in-phase and quadrature phase signals to vertical and horizontal comparison boundary member pairs. The comparator circuit also includes a tilted comparison circuit, coupled to the non-tilted comparison circuit, that compares the resultant vector to comparison boundary member diagonals coupled to the vertical and horizontal comparison boundary member pairs. The comparator circuit may still further include a combiner circuit that provides a comparison signal based on signals from the non-tilted and tilted comparison circuits.
