Gain and Bandwidth Enhanced Class-AB OTAs
2019 IEEE 62nd International Midwest Symposium on Circuits and Systems (MWSCAS), 2019Efficient class-AB OTAs with enhanced gain bandwidth, open loop gain, output current, and slew rate are presented. They are based on a g m -boosting technique (at least factor of two) and also use dynamically biased cascode transistors to achieve high gain and output currents much larger than the bias current.

Multichannel Speech Enhancement with Gains
2011In the previous two chapters, we exploited the temporal information from a single microphone signal to derive different techniques for speech enhancement in the STFT domain. In this chapter and the next one, we will exploit both the temporal and spatial information available from signals picked up by a determined number of microphones at different ...

Enhanced Gain Patch Antennas at Millimeter Waves
27th European Microwave Conference, 1997, 1997A study of a rectangular patch, with a dielectric plate installed in front of the patch at a "resonant" distance, has been performed at the upper Ka frequency band. For this purpose three antennas have been designed, analyzed, built and measured. These antennas are: a "conventional" rectangular patch; an enhanced gain rectangular patch (a "conventional"

Enhancing genetic gain in the era of molecular breeding
Journal of Experimental Botany, 2017As one of the important concepts in conventional quantitative genetics and breeding, genetic gain can be defined as the amount of increase in performance that is achieved annually through artificial selection. To develop pro ducts that meet the increasing demand of mankind, especially for food and feed, in addition to various industrial uses, breeders ...

A gain-adaptive parallel HMM for speech enhancement
2015 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA), 2015This document is an example of what your final camera-ready manuscript to APSIPA ASC 2015 should look like. Authors are asked to conform to the directions reported in this document. The key problem in Hidden Markov model (HMM)-based speech enhancement is how to obtain an appropriate weighted Wiener filter (WWF).

Excitonic enhancement of optical gain in quantum wells
Physical Review B, 1995Excitonic effects of optical gain in quantum wells have been studied theoretically in a three-band model. Taking into account an additional localized level in the energy gap, we obtain the optical gain in terms of the transition between a localized state and a continuous subband state with small carrier concentration.

Enhanced x-ray gain through photodepopulation
Physical Review A, 1988Radiation trapping currently creates one of the major limitations on population inversion, gain, and size in x-ray lasers. The resulting increase in lower-level population may be reduced by photodepletion to higher energy levels. A natural energy match between hydrogenic lasing ions of nuclear charge Z, for n = 2 to 4 or 6 excitation, and Z/2 radiating
