in this paper, a high speed delay-locked loop (dll) architecture ispresented which can be employed in high frequency applications. in order to design the new architecture, a new mixed structure is presented for phase detector (pd) and charge pump (cp) which canbe triggered by double edges of the input signals. in addition, the blind zone is removed due to the elimination of reset signal. theref...

High speed ADCs are used in a wide variety of real-time DSP signal-processing applications, replacing systems that used analog techniques alone. The major reason for using digital signal processing are (1) the cost of DSP processors has gone down, (2) their speed and computational power has increased, and (3) they are reprogrammable, thereby allowing for system performance upgrades without hard...

High Speed Integrated Circuits for High Speed Coherent Optical Communications by Hyun-chul Park With the development of (sub) THz transistor technologies, high speed integrated circuits up to sub-THz frequencies are now feasible. These high speed and wide bandwidth ICs can improve the performance of optical components, coherent optical fiber communication, and imaging systems. In current optica...

The implicit conception of conscience from Ludwig Wittgenstein’s notes 1929 is brought into comparison with the theory as a paradoxical identity guilt and innocence by Philip Konrad Marheineke (which served pattern for Kierkegaardian concept “despair”) (grammatical temporal) redoubling Vladimir Jankélévitch. Wittgensteinian views on feeling tend to Marheineke-Kierkegaard’s model (the hides in v...

We report the observation of the electrochemically generated nitrenium ions of 4,4'-dimethyoxydiphenylamine and di-p-tolylamine in solution by mass spectrometry. This setup takes inspiration from desorption electrospray ionization mass spectrometry to sample directly from the surface of a rotating waterwheel working electrode for mass spectrometric analysis. Detection of the 4,4'-dimethyoxydiph...

Modern database clusters entail two levels of networks: connecting CPUs and NUMA regions inside a single server in the small and multiple servers in the large. The huge performance gap between these two types of networks used to slow down distributed query processing to such an extent that a cluster of machines actually performed worse than a single many-core server. The increased main-memory c...
