2008 IEEE Custom Integrated Circuits Conference, 2008
A digitally-controlled oscillator (DCO) for mm-wave wireless applications is demonstrated for the first time. Low phase noise is achieved adopting an efficient complementary topology and optimizing the programmable-capacitor array. A fine frequency resolution of 1.8 MHz is obtained using switched metal-oxide-metal capacitors while coarse frequency ...

An Optimum DC-Biasing for DCO-OFDM System
IEEE Communications Letters, 2014Selecting an appropriate direct current (dc) bias is crucial to obtain positive and low-peak-to-average-power-ratio electrical signals in the dc optical orthogonal frequency-division multiplexing (DCO-OFDM) system. In this letter, our goal is to propose an optimization strategy of dc bias under given lower and upper clipping bounds. We characterize the

Bend–stretch Fermi resonance in DCO+
The Journal of Chemical Physics, 2002Rydberg series, rovibrationally isolated by double resonant excitation, are extrapolated to determine rotational-state detailed ionization thresholds to form DCO+ in the bending-excited levels (030) and (040). Analysis of the rovibrational structure derived from the positions of these thresholds for (030) agrees with a simple parameterization extended ...

The Role of Dco in \kur{Drosophila} Haematopoiesis
, 2012 Point mutations found in human breast cancer samples introduced into the Drosophila dco gene affect the Drosophila haematopoiesis. I described different haematopoietic phenotypes in such mutants and tested their connection with the Toll and the JAK/STAT signalling pathways.

A high-accuracy DCO with hybrid architecture
Journal of Semiconductors, 2017In this paper, a novel hybrid digital-controlled oscillator (DCO) is proposed, which is used to improve the accuracy of the all-digital clock generator without reference source. The DCO with hybrid architecture consists of two parts: DCO_high and DCO_low.

A high-resolution DCO with MOS capacitors
2012 24th International Conference on Microelectronics (ICM), 2012A digitally controlled oscillator (DCO) that achieves a minimum frequency tuning step of 20 kHz without any dithering is presented. Three tuning stages are employed to obtain a wide frequency range of 1 GHz in the classical LC tank. The fine tuning bank is realized by inverse connection of two pairs of pMOS transistors and a tiny unit capacitance of 0 ...

Myers and Benson (1983) conducted a survey of nearby molecular cores for NH3. They identified 27 such cores, with an average TK ~ 10 K and an average density of 104. This sample allows one to investigate physical conditions in low mass cores, with a variety of techniques.

An experimental measure of anharmonicity in the bending of DCO+
The Journal of Chemical Physics, 2001Rydberg series of DCO have been rovibrationally isolated by double resonance and extrapolated to produce a map, with sub-wave-number accuracy, of individual rotational level positions in the bending fundamental and first overtone of DCO+. Analysis of this structure determines fundamental frequencies, rotational constants, and low-order anharmonicities ...
