LinuxBIOS is fast becoming a widely accepted alternative to the traditional PC BIOS for cluster computing applications. However, in the process it is gaining attention from developers of Internet appliance, desktop and visualization applications, who also wish to take advantage of the features provided by LinuxBIOS, such as minimizing user interaction, increasing system reliability, and faster ...

A newly proposed variable gain amplifier (VGA) topology is presented. The three-stage VGA offers a wide control gain range, which is independent on process variation, and is characterized by low-power, high linearity, wide range of control signal, and small chip size characteristics. The VGA is fabricated in 0.18μm CMOS technology and measurements show a gain variation of 83dB (-36~47dB) with a...

In this paper, an Automatic Gain Control (AGC) loop which is based on a linear-in-dB Variable Gain Amplifier (VGA) is proposed. The VGA structure is based on simple nMOS differential pairs with variable tail currents. The linear-in-dB gain tuning schema is designed using a novel exponential current generator which also offers temperature compensation of the VGA’s gain. The gain of the VGA is tu...

BACKGROUND Traumatic brain injury is a leading cause of death and severe neurologic disability. The effect of anesthesia techniques on neurologic outcomes in traumatic brain injury and potential benefits of total intravenous anesthesia (TIVA) compared with volatile gas anesthesia (VGA), although proposed, has not been well evaluated. The purpose of this study was to compare TIVA versus VGA in p...

SUMMARY RF Variable Gain Amplifiers (RF-VGA) are important components for integrated TV broadcast receivers. Analog and digital controlled RF-VGAs are compared in terms of linearity and an AGC loop architecture suitable for digitally controlled RF-VGA is proposed. Further linearity enhancement applicable for CMOS implementation is also discussed .

The present paper depicts visualization of temperatures on Video Graphics Array (VGA) monitor; using no central processing units (CPUs). It displays the temperatures sensed by multiple sensors, concurrently. Instead of reading the physical parameters on numerical display panels, or observing those on a personnel computer (PC) based system; the instrumentation was developed in such a way that, t...

In this study, the effects of annealing on surface residual impurities and intrinsic defects unintentionally doped (UID) β-Ga2O3 are investigated by adopting high-temperature thermal treatments at 1000 °C for 1 h under vacuum O2 ambience. It is found that recovery between divacancies VGa+VO interstitials (Oi) occurs during annealing, identified as Si Cr, which repelled toward annealing. Interes...

A CMOS Variable Gain Amplifier (VGA) is proposed for high frequency and low power broadband communication systems, such as Ultra-Wide Band (UWB) receiver. The VGA consists of a P/NMOS complimentary differential-pair with source degeneration, a high-swing current mirror stage with capacitive feedforward frequency compensation, and resistive load. Description Based on an OFDM UWB receiver system’...
