The oscillation test methodology is presented for active RC filters. The authors develop general guidelines for the design of the oscillation-based test structures and describe in more detail 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. The presented test structures can also be employed for stimulus generation in a built-in self-test.
