--In this paper, we proposed a new dual threshold circuit technique for reduction of subthreshold and static power dissipation. When the scaling down technology the threshold voltage takes place, due to increasing the leakage current. In this method, n-type and ptype transistor are introduced between the pull up and pull down network, the gateof inserting transistors is connected to the respect...

the natural frequency and pull-in instability of clamped-clamped nano-actuators in the presence of a dielectric layer are analyzed. the influence of the presence of casimir force, electrostatic force, fringing field effect, axial force, stretching effects and the size effect are taken into account. the governing equation of the dynamic response of the actuator is transformed in a non-dimensiona...

This paper presents an approach for simulation of mixedsignal CMOS integrated circuits, aiming at estimating crosstalk effects, by identifying possible sources of disturbances in analog-digital integrated systems, such as current pulses drawn from voltage supplies. A simple expression of voltage and current in the pull-up and the pull-down of a CMOS logic gate can be derived. A computer program...

This paper describes an electrostatic excited microcantilever sensor operating in static mode that is more sensitive than traditional microcantilevers. The proposed sensor comprises a simple microcantilever with electrostatic excitation ability and an optical or piezoresistive detector. Initially the microcantilever is excited by electrostatic force to near pull-in voltage. The nonlinear behavi...

This paper investigates the design and performance of the PLL (Phase Locked Loop). The proposed PLL designed with PFD (Phase Frequency Detector), CP (Charge Pump), first order Low Pass Filter and CS-VCO (Current Starved-Voltage Control Oscillator), in this paper the designed PFD used for proposed PLL is free from dead zone. The VCO used for the designed PLL shows larger tuning range and high ga...

Interest in vibration energy harvesting technologies has increased significantly in the last decade, primarily due to the possibility of realizing ultra-low power sensor and communication circuits. In such low-power applications, it is paramount to maximize the efficiency of the harvesting system. Here, we propose the use of a simple MEMS cantilever as a power regulating hysteretic switch that ...

We consider a parabolic problem with Robin boundary condition which arises when the edge of micro-electro-mechanical-system (MEMS) device is connected flexible nonideal support.

A pumping system powered from Photovoltaic array is modeled and simulated using Matlab Simulink. Detailed evaluation of energy processing in Photovoltaic pumping system is presented. A low voltage DC is stepped by using DC to DC Push -Pull converter. DC output from the PV Cell is converted into high frequency AC using a Push Pull Inverter. This is stepped up to 200v using a high frequency steps...

Abstract. Dual threshold voltage and forward body bias techniques are effective ways to optimally balance the standby leakage power and performance. In this paper, we propose a novel fine-grained forward body biasing scheme for monotonic static logic circuits. In the proposed scheme, the forward body bias is applied to high threshold voltage of either the pull-up or the pull-down network based ...
