Abstract:
There is a growing need to analyze and optimize the stand-by component of power in digital circuits designed for portable and battery-powered applications. Since these circuits remain in stand-by (or sleep) mode significantly longer than in active mode, their stand-by current, and not their active switching current, determines their battery life. Hence, stringent specifications are being placed on the stand-by (or leakage) current drawn by such devices. As the power supply voltage is reduced, the threshold voltage of transistors is scaled down to maintain a constant switching speed. Since redu

Abstract:
Deep pipeline has traditionally been widely used in high performance microprocessor. To allow continuous program execution, branch prediction provides a necessary method of speculatively executing instructions without compromising performance. However, branch misprediction penalty significantly impacts the performance of the deep pipeline processor. This study presents a new Adaptive Pipeline Voltage Scaling (APVS) technique to reduce branch misprediction penalty. For a likely mispredicted branch entering the processor, APVS begins increasing voltage and merging deep pipeline whereby shorter p

Abstract:
In this study, an adaptive driving method for synchronous rectification in bidirectional full-bridge LLC resonant converters used in railway applications is proposed. The drain to source voltage of the synchronous rectifier is utilized to detect the conduction of the body diode, and a suitable driving signal for synchronous rectification is generated accordingly. The proposed driving scheme is simple and can be realized using a low-cost digital signal processor (DSP). According to the experimental results, which averaged 0.4625% and 1.097%, improvement can be observed under charging and discha

This paper proposes a new adaptive filter for wind generators that combines instantaneous reactive power compensation technology and current prediction controller, and therefore this system is characterized by low harmonic distortion, high power factor, and small DC-link voltage variations during load disturbances. The performance of the system was first simulated using MATLAB/Simulink, and the possibility of an adaptive digital low-pass filter eliminating current harmonics was confirmed in steady and transient states.

The integrated fast lattice filter adaptive control algorithm developed in Part 1 of this paper will be implemented for the control of the structural vibration of a coordinate measuring machine (CMM). The structural vibration of a CMM exhibits time-varying dynamic characteristics. For auxiliary control, the probe head acceleration was measured to compute the voltage input to the servo motor of the CMM. The developed algorithm uses directly the lattice filter parameters to track and control the CMM structural dynamics and is implemented on a Sheffield horizontal arm Coordinate Measuring Machine

Abstract:
The Dynamic Voltage Scaling (DVS) technique has proven to be ideal in regard to balancing performance and energy consumption of a processor since it allows for almost cubic reduction in dynamic power consumption with only a nearly linear reduction in performance. Due to its virtue, the DVS technique has been used for the two main purposes: energy-saving and temperature reduction. However, recently, a Dynamic Voltage Scaled (DVS) processor has lost its appeal as process technology advances due to the increasing Process, Voltage and Temperature (PVT) variations.
