Lossless/lossy image compression based on non-separable two-dimensional L-SSKF
In this report, we propose a non-separable twodimensional (2D) Lossless Symmetric Short Kernel Filter (L-SSKF) for image compression. Filter characteristics of our proposed L-SSKF...

High-speed pipelined A/D converter using time-shifted CDS technique
A time-shifted correlated double sampling (CDS) technique is used to compensate for the finite opamp dc gain in the context of a pipelined analog-to-digital converter (ADC). This...
