A method and radiation hardened phase frequency detector (PFD) for implementing enhanced radiation immunity performance, and a design structure on which the subject PFD circuit resides are provided. The radiation hardened phase frequency detector (PFD) includes a plurality of functional blocks. Each functional block includes duplicated components providing duplicated inputs, internal nodes and outputs. The duplicated components are arranged so that when there is a SEU hit to one node and the duplicated node supports the functionalities of the PFD.
