This paper analyzes the impact of clock skew between comparators in a flash ADC, showing that the SNDR penalty introduced by this effect can become significant at high frequencies. To address this issue, a passive resonant clock network is proposed to distribute the clock to the comparators in a flash ADC. The inductive termination of this network serves to resonate out the parasitic and input capacitances...
One-dimensional threshold segmentation algorithm has poor adaptability and poor noise immunity, while two-dimensional threshold segmentation has high computational complexity. To solve these problems, we propose a novel threshold segmentation algorithm for image segmentation. The whole method contains three steps: constructing one-dimensional histogram by using each pixel's gray value and its surrounding...
