Abstract
A programmable logic array implemented with complementary insulated-gate field effect transistor technology and formed on a substrate employing a standard AND-OR structure and two non-overlapping clock phases uses diffused capacitors in a dummy row to model the worst case evaluation time of minterms in the AND plane, and a NOR gate, responsive to the dummy row, for enabling the OR plane to sum the minterms generated by the AND plane.
