Abstract
Conventional SC realizations of wideband filters demand large capacitance spread and exhibit serious sensitivity problems. The UL-LU structure is a ladder type simulation which demonstrates superior sensitivity performance and maintains low capacitance spread. The design illustrates how the facilities of a modern filter compiler can be utilized to solve some quite difficult practical problems in a real application. Results from fabricated devices confirm the predicted properties
