AN EXTENDED RESONATOR CONCEPT AND ITS APPLICATION IN SWITCHED-CAPACITOR DFT PROCESSORS

An extension of the method based on the Goertzel-algorithm is given applying general two-output second-order lossless discrete resonators. In the proposed structure of resonators simple SC integrators are used avoiding the problems of circuit complexity of SC delay elements. The different resonators of the bank are of the same topology and differ only by one capacitor value. The solution is, therefore, very suitable for integration.
