The flicker noise mechanism under switching conditions is studied. Experimental results show that the baseband flicker noise is a superposition of upconverted gate flicker noise at each harmonic of the output current. Methods to reduce the flicker noise are discussed. Based on the measured results, the large signal flicker noise model for RF applications under switching conditions is proposed a...

Focus+context techniques provide visual guidance in visualizations by giving strong visual prominence to elements of interest while the context is suppressed. However, finding a visual feature to enhance for the focus to pop out from its context in a large dynamic scene, while leading to minimal visual deformation and subjective disturbance, is challenging. This paper proposes Attractive Flicke...

Introduction:GaAsySb1-y/In0xGa1-xAs based III-V staggered hetero-junction Tunnel Field Effect Transistors were demonstrated with MOSFET-like high drive currents at low Vds [1], demonstrating feasibility of TFETs to scale supply voltage for future low power logic applications. More than 2x enhancement in Ion was demonstrated over the In0.7Ga0.3As homo-junction counterpart due to reduction in the...

The chapter covers general issues related to power quality in Electric Arc Furnaces. The use of electric arc furnaces (EAF) for steelmaking has grown dramatically in the last decade. Of the steel made today 36% is produced by the electric arc furnace route and this share will increase to 50 by 2030. The electric arc furnaces are used for melting and refining metals, mainly iron in the steel pro...

This article proposes a novel algorithm employing space vector ellipse (SVE) in complex plane to classify and visualize power quality disturbance-events (PQDEs). In the proposed method, at first, time-domain signal reference signal, which are separated by 90°, mapped 2D coordinates. Thus, tip of resultant rotating traces an ellipse, from three parameters, namely, semi-major axis, semi-minor axi...

In this paper, a 1.2-V RF front-end realized for the personal communications services (PCS) direct conversion receiver is presented. The RF front-end comprises a low-noise amplifier (LNA), quadrature mixers, and active RC low-pass filters with gain control. Quadrature local oscillator (LO) signals are generated on chip by a double-frequency voltage-controlled oscillator (VCO) and frequency divi...

A fully differential opamp suitable for very-low voltage switched-capacitor circuits in standard CMOS technologies is introduced. The proposed two stage opamp needs a simple low voltage CMFB switched-capacitor circuit only for the second stage. Due to the reduced supply voltage, the CMFB circuit is implemented using bootstrapped switches. Minor modifications allow to use chopper stabilization f...

The voltage flicker is main factor influencing the power quality and SVC is well-proven solution. The flicker reduction requires very short response time, according to the relation analysis between flicker improvement factor and response time. SVC has a fast open-loop control function to achieve effective voltage support. The fast algorithm of flicker reduction is presented here based on synchr...

The generation of additional interface traps in the pinch-off region and the threshold voltage shift due to hotelectron stressing have been shown to cause 1-3 orders of magnitude increase in the flicker noise density. This flicker noise “overshoot” can easily degrade the performance/resolution of analog circuits by 6-18dB. An improved flicker noise model which is capable of accurately predictin...
