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.
