This paper presents key design techniques and challenges in implementing one of the first integrated, energy-efficient 60GHz transceivers including baseband circuitry. The 90nm CMOS direct-conversion design (Fig. 18.5.1) operates from a 1.2V supply and has been optimized for 5-to-10Gb/s QPSK modulation centered at 60GHz. To achieve power consumption of(More)
BACKGROUND Distant hybridization can result genome duplication and allopolyploid formation which may play a significant role in the origin and evolution of many plant species. It is unclear how the two or more divergent genomes coordinate in one nucleus with a single parental cytoplasm within allopolyploids. We used cytological and molecular methods to(More)
Interkinetic nuclear migration (INM) is a key feature of cortical neurogenesis. INM functions to maximize the output of the neuroepithelium, and more importantly, balance the self-renewal and differentiation of the progenitors. Although INM has been reported to be highly correlated with the cell cycle, little is known about the effects of cell cycle(More)
Emerging applications for the 60GHz spectrum include extremely high-data-rate short-range communication systems. Many of these applications are expected to enter the realm of consumer electronics where low cost and mass production are prerequisites, favoring the application of digital CMOS technology. In this paper, a highly integrated receiver front-end is(More)
A low power inductorless wideband variable gain control amplifier (VGA) for baseband receivers has been designed in a standard digital 90 nm CMOS technology. The VGA was implemented using four-stage modified Cherry-Hooper amplifier with a dual feedback DC-offset canceling network, which simultaneously corrects DC offsets and extends bandwidth without a(More)
—This paper presents a novel CMOS impulse radio (IR) ultra-wide-band (UWB) transceiver system design for future contact less chip testing applications using inductive magnetic coupling as wireless interconnect. The proposed architecture is composed of a simple and robust design of a Gaussian Monocycle impulse generator at the transmitter, a wideband(More)
Building tertiary structures of non-coding RNA is required to understand their functions and design new molecules. Current algorithms of RNA tertiary structure prediction give satisfactory accuracy only for small size and simple topology and many of them need manual manipulation. Here, we present an automated and fast program, 3dRNA, for RNA tertiary(More)
Image segmentation is the first essential and important step of low level vision. This paper proposes a novel algorithm for adaptive image segmentation, based on thresholding technique and segments merging according to their characteristics combine with spatial position. Our earlier work of getting the entire information of the histogram could help choose(More)
