Abstract :
This paper introduces a circuit of MEMS capacitive switches, which yields a set of phase states that are close to being equally separated. The optimal capacitance values of the switches are determined using a genetic algorithm (GA). In addition, a ternary design for controlling the switches is proposed to reduce the number of control lines required without decreasing the number of realizable phase states.
