In this paper static and dynamic response of nanotweezers composed of two carbon nanotube (CNT) arms are investigated. Taking into account a continuum model and considering the electrostatic actuation as well as the presence of the van der Waals forces, the static nonlinear equations are solved by a step by step linearization and Galerkin projection method. Simulating the closing dynamics of a ...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...

In this paper, static and dynamic behavior of a varactor of a micro-phase shifter under DC, step DC and AC voltages and effects of the residual stress on the phase diagram have been studied. By presenting a mathematical modeling, Galerkin-based step by step linearization method (SSLM) and Galerkin-based reduced order model have been used to solve the governing static and dynamic equations, resp...

Static circuit gates are the standard circuit devices used to build the major parts of digital circuits. Dynamic gates, such as domino circuits, are only used in certain sections of the circuit where speed is critical. These gates achieve higher speed compared to static gates at the cost of reduced noise margins. We propose a novel gate structure that tries to improved noise margin when compare...

This study develops a continuous model to analyze the ‘pull-in’ effect in the circular micro-plates used in capacitive-type micro-electro-mechanical systems (MEMS) sensors, actuators and microphones. In developing the model, the governing equation of motion of the deformed plate is established in the form of a partial different equation (PDE) which is then decomposed using the Galerkin method t...

This paper presents a 372ps 64-bit adder using Fast Pull-up Logic (FPL) in 0.18 μm CMOS technology. Fast Pullup Logic is devised and applied to decrease pull-up time which is critical in domino-static adder. The implemented adder measures the worst case delay of 372ps. The adder has a modified tree architecture using Load Distribution Method and has 6 logic stages.
