This paper presents the energy analysis of capacitive adiabatic logic (CAL) based on gap-closing MEMS devices. CAL uses variable capacitance components instead of transistor elements to have a new balance between on- and off-state losses. Ultra-low power consumption in CAL requires an energy efficient way for charging and discharging of the variable capacitance. First, we investigate “pure” electrical...
This paper presents a design of a capacitive double beam MEMS microswitch based on dynamic pull-in actuation. The design consists of two suspended microbeams actuated by an electrostatic nonlinear force accounting for fringing field effect. The applied force controls the ON and the OFF states of the microswitch using a variable voltage. We first develop a mathematical model for the MEMS microswitch,...
This study proposes the use of a new actuation technique to trigger ON/OFF states of a capacitive microswitch. The proposed technique is compatible with CMOS technology thanks to its low and simple actuation voltage. Using a reduced-order model based on the Differential Quadrature Method, which fully incorporate the electrostatic force nonlinearities, we solve for static, transient and limit-cycle...
In this paper, we propose the design of an ohmic contact RF microswitch with low voltage actuation, where the upper and lower microplates are displaceable. We develop a mathematical model for the RF microswitch made up of two electrostatically actuated microplates; each microplate is attached to the end of a microcantilever. We assume that the microbeams are flexible and that the microplates are rigid...
