Theory of self-induced resonances in asymmetric two-junction interferometer device is presented. An extension of previous theoretical approaches contains inclusions from several asymmetries: the Josephson current ε, capacitances χand dissipation ρpresented in an equivalent circuit. Our theory can be useful to determine asymmetry parameters always present in lightly damped asymmetric SQUIDs made from low- and high-T_C materials.
