Abstract :
This work presents a design for test method for continuous time active filters of any order, using the IEEE 1149.4 as its backbone structure. The method relies on the synthesis of filter transfer functions using partial fraction extraction. Transfer functions are built from 1st order blocks connected via the available standard infrastructure. Under this approach, structural test can be carried out using simple test vectors, which are disclosed according to a fault simulation process.
