An improved clock-feedthrough compensation scheme for switched current system is proposed. Both the signal dependent and the constant clock-feedthrough terms are canceled by using both nMOS and pMOS current samplers and by adopting a source replication technique. The proposed current memory cell was fabricated with 0.6m CMOS process. Both experimental and theoretical results on clockfeedthrough...

We present an algorithm suitable for the compensation of flicker in archived film sequences. The proposed method is a substantial improvement over our previous work which adopted a nonlinear approach to flicker compensation motivated by fundamental principles of photographic image registration. The improvements include reliability weighting, spatial adaptation and motion compensated weighting. ...

A curvature compensation technique for bandgap voltage references that utilizes an adaptive reference temperature is presented. This compensation technique is intended for high-resolution temperature-stable analogdigital converters. A test circuit had been designed in a 0.6 μm CMOS technology to implement this technique. The reference voltage has a simulated temperature coefficient of 2.3 ppm/ ...

We theoretically evaluate the prediction efficiency of the overlapped block motion compensation (OBMC) compared with the conventional non-overlapped approach. Based on the one-dimensional signal model characterized by the AR(1) process and first-order polynomial motion, a condition under which the performance of the OBMC is better, and an optimum window function are derived. From the results, w...

In this paper, we report on our efforts toward developing a multiscale segmentation based video compression algorithm aimed at very low bit-rate applications such as video teleconferencing and video phones. We introduce novel techniques for multiscale segmentation based motion compensation and residual coding. Our region based forward motion compensation strategy (in terms of direction of motio...

This paper investigates advanced channel compensation techniques for the purpose of improving i-vector speaker verification performance in the presence of high intersession variability using the NIST 2008 and 2010 SRE corpora. The performance of four channel compensation techniques: (a) weighted maximum margin criterion (WMMC), (b) source-normalized WMMC (SN-WMMC), (c) weighted linear discrimin...

Background. Athletes’ performance in sporting events is influenced by several factors. One of them is how fair the compensation system is implemented. The proper compensation will motivate the athlete to perform better. Otherwise, it will be a loss for the team. Objectives. The purpose of this study was to determine the effect of compensation on the sports achievements of South Sulawesi athlet...
