FIG. 3B is a drawing of an equivalent circuit 200 of the micro-electro-mechanical system varactor 100 of FIG. 2C. As in FIG. 2C, a bias voltage 160 having a magnitude greater than a specified value is applied between the upper bias conductor 166 and the lower bias conductor 165 which results in pulling the top conductor 140 into physical contact with the dielectric layer 130.
