In this paper we present the oscillation test methodology for active RC filters. We develop general guidelines for the design of the oscillation-based test structures and describe in more details test transformations of filter configurations which are most frequently used in practice. Frequency measurements performed on some implemented test structures and fault detection experimental results are included. The oscillation-based test described in this paper is primarily intended for field testing. In some cases, it can also be used as a functional go no-go test in production. Presented test structures can also be employed for stimulus generation in a built-in self-test.
