In this paper, a new approach for concurrent checking by Berger codes is proposed. We modify a subset of outputs of the original circuit by adding modulo 2 the outputs of a complementary circuit. In the error free case, the unmodified outputs together with their corresponding modified outputs are elements of a Berger code. The number of outputs of the original circuit does not increase. Compared to the traditional method of concurrent checking by Berger codes, a smaller checker is needed.
