In this paper, we propose a closed form method to evaluate the read stability of an SRAM cell via quartic root finding. By utilizing a simplified MOSFET device model, we model SRAM cell stability by a system of quartic equations. The algebraic nature of the equations along with simplified region boundaries provide the insight that only a few combinations of device operating regions correspond to the...
This paper describes MAISE, an embedded linear circuit simulator for use mainly within timing and noise analysis tools. MAISE achieves the fastest possible analysis performance over a wide range of circuit sizes and topologies by an adaptive architecture that allows applying the most efficient combination of model reduction algorithms and linear solvers for each class of circuits. The main pillar...
This paper extends the range of generalized predictive control (GPC) algorithm proposed by Clark et al. based on a CARIMA model, and shows that it is also applicable for an ARMAX model and a CARMA model. Unified formulas are given to provide direct approach to GPC using model parameters without solving Diophantine equations. The extended GPC is applied for the control of a pneumatic actuator based...
Due to the current resource crisis, reliable electrical loss analysis and prediction attract more attention than ever for efficient power system management. This paper successfully predicts the electrical loss of ACSR with actual daily load variations using an accurate and effective neural network model, which is validated by visual comparison and strict statistical criterion. Since electrical loss...
For the purpose of power system safety and reliability, conductor maintenance and design, mechanical properties of ACSR have been intensively discussed and studied through a sample conductor. The variations of strain and sag with current, service of time, and actual daily load demands are computed using a novel iterative procedure implemented in a Visual C++ software package, and predicted with an...
This paper proposes a novel design procedure of fuzzy logic controller (FLC) for DC-to-DC converters that integrates linear control techniques with fuzzy logic. The design procedure allows the small signal model of power converters and linear control design techniques to be used in the initial stages of FLC design. This simplifies the small signal design and the stability assessment of the FLC. By...
In this paper, a new resonant gate drive circuit is proposed. The proposed circuit consists of four control switches and a small resonant inductance. The current through the resonant inductance is discontinuous in order to minimize circulating current conduction loss present in other methods. The proposed circuit also achieves quick turn-on and turn-off transition times to reduce switching loss and...
A new duty cycle parallel control method for AC-DC converter with power factor correction is proposed. The duty cycle required to achieve unity power factor consists of two terms: current term and voltage term. They are calculated directly based on the reference current and sensed inductor current, input voltage and output voltage. It requires only one multiplication and three addition operations...
An artificial neural network (NN) has been implemented in the explosives detection systems fielded at various airports. Tests of the online performance of the NN confirmed its superiority over standard statistical techniques; and the NN was installed as the decision algorithm. Analysis of the mass of data being produced is still underway, but preliminary conclusions are presented. Results are given...
