Many multimedia and DSP applications are highly multiplication intensive so that the performance and power consumption of these systems are dominated by multipliers. The computation of the multipliers manipulates two input data to generate many partial products for subsequent addition operations, which in the CMOS circuit design requires many switching activities. Thus, switching activity withi...

An EMI filter for a three-phase buck-type medium power pulse-width modulation rectifier is designed. This filter considers differential mode noise and complies with MIL-STD461E for the frequency range of 10kHz to 10MHz. In industrial applications, the frequency range of the standard starts at 150kHz and the designer typically uses a switching frequency of 28kHz because the fifth harmonic is out...

Gate-sizing is an effective technique to optimize CMOS circuits for dynamic power dissipation and performance while dual-V,h (threshold voltage) CMOS is ideal for leakage power reduction in low voltage circuits. This paper focuses on simultaneous dual-V,h assignment and gate-sizing t o minimize the total power dissipation while maintaining high performance. An accurate power dissipation model t...

This paper we proposed advanced burst mode control technique to reduce the standby power consumption of the switch mode power supply (SMPS). To reduce the standby power consumption, most of the converter use burst mode or skip mode control technique. However Conventional standby mode control techniques have some problems such as audible noise and poor regulation. In proposed techniques, basical...

A small footprint integrated Membrane InP Switch (MIPS) on Silicon-On-Insulator (SOI) is demonstrated for use in all-optical packet switching. The device consists of an optically pumped III-V membrane waveguide of only 100 nm thick, coupled to the underlying SOI waveguide circuit. Because of its limited thickness, the optical confinement in the active layers is maximized, allowing for high exti...

An improved single-ended push–pull (SEPP) halfbridge type zero-voltage soft-switching pulse width modulation (ZVS-PWM) DC–DC power converter is presented in this paper, which makes use of a saturable reactor-assisted lossless capacitor type zero voltage soft-switching method. The SEPP power converter with a high-frequency forward and flyback hybrid transformer link has some advantages such as l...

The power consumption of a digital circuit can be reduced by decomposing it into sub circuits which can be turned off when inactive. Power can also be reduced by careful state encoding. Clock-gating techniques have been shown to be very effective in the reduction of the switching activity in sequential logic circuits. Modeling a given circuit as a finite-state machine, we formulate its decompos...
