This paper reports an electrical equivalent circuit model for describing in-plane two degree-of-freedom comb transducers. The proposed model is valid for any external parameters by building dummy spring into mis model to detect a mechanical displacement. As a result, we can analyze dc operating points by the model so that we need not to change the parameters of the model on changing the connected electrical and mechanical components, such as a dc bias, external force, and the stiffness of a spring. This model was adapted to a resonator and a frequency characteristic of 2DOF comb transducers was well represented by the model.
