Layout has strong influence on matching properties of a circuit. Current matching models, which characterize both local random non-uniformities and global systematic non-uniformities stochastically, are not adequate for the matching analysis taking the effect of layout realization into account. In order to consider topological information of layout into matching analysis, we propose a matching ...

A practical adaptive compression algorithm based on LZSS is presented, which is especially constructed to solve the compressed pattern matching problem, i.e., pattern matching directly in a compressed text without decompressing.

A new current-mode Tow-Thomas biquad filter based on employing current differencing transconductance amplifiers (CDTAs) is introduced. The filter circuit uses two grounded capacitors and realizes a lowpass (LP) and a bandpass (BP) responses, simultaneously. The proposed circuit is electronically tunable by adjusting the biasing current of the CDTAs. The circuit requires no component matching co...

In natural signals, such as the luminance value across of a visual scene, abrupt changes in intensity value are often more relevant to an organism than intensity values at other positions and times. Thus to reduce redundancy, sensory systems are specialized to detect the times and amplitudes of informative abrupt changes in the input stream rather than coding the intensity values at all times. ...

A new stereo matching algorithm is introduced that performs iterative refinement on the results of adaptive support-weight stereo matching. During each iteration of disparity refinement, adaptive support-weights are used by the algorithm to penalize disparity differences within local windows. Analytical results show that the addition of iterative refinement to adaptive support-weight stereo mat...
