High-speed op amps come in current- and voltage-feedback versions. Voltage-feedback amplifiers are sometimes de-compensated to allow greater speed, but this technique has been superceded by current-feedback amplifiers. Differential-output op amps are gaining popularity for transformerless A

Abstract – In the development of an interior permanent magnet synchronous machine (IPMSM) for high-speed operation, the problem of mechanical stress of the rotor by centrifugal force becomes more essential as the speed and size of the machines increase. In this paper, the optimal design process com

Simulation modeling can be highly effective for solving problems found in the food, beverage, consumer products, and pharmaceutical industries. The flow of material or fluid in these industries is often described as bulk flow, continuous, semi-continuous, or high-speed. Traditional discrete event

High speed analog signal processing applications, such as video and communications, require op amps which have wide bandwidth, fast settling time, low distortion and noise, high output current, good DC performance, and operate at low supply voltages. These devices are widely used as gain blocks

CMOS continuous-time and switched-capacitor filters which operate at high frequencies with high Quality factor Q are difficult to realize. The finite gain and the finite bandwidth of the integrator amplifiers are the main limitation. This paper describes two techniques to simultaneously increase

ABSTRACT The aim of the work described in this paper is to improve the dynamic performance of a one-degree-of-freedom packaging mechanism through demand signal shaping to minimize the peak to peak motor torque. This enables the mechanism to operate at higher speeds with lower vibration and noise

Abstract: A method is presented which allows for the experimental determination of the characteristics of brushless PM synchronous machine parameters in the high speed operating range. The theory and real-time implementation is described for this computer based parameter identification method

by ultrasmall device movable volumes (at ~1μm3 level) and contact areas (only ~0.01–0.1μm2), and challenging contact resistances (can be from ~10kΩ to ~100MΩ). We perform time-domain AC characterization of SiC NEMS switches with operating speeds up to 1kHz and high on/off current ratios of ~106. For multiple

This paper proposes a constant-load SRAM design for highly efficient recovery of bit-line energy with a resonant power-clock supply. For each bit-line pair, the proposed SRAM includes a dummy bit-line of sufficient capacitance to ensure that the memory array presents a constant capacitive load
