A 10-Gb/s phase-locked clock and data recovery circuit incorporates an interpolating voltage-controlled oscillator and a half-rate phase detector. The phase detector provides a linear characteristic while retiming and demultiplexing the data with no systematic phase offset. Fabricated in a 0.18m CMOS technology in an area of 1 1 0 9 mm, the circuit exhibits an RMS jitter of 1 ps, a peak-to-peak...

We show that two identical solid-state qubits can be made fully entangled ~starting from a completely mixed state! with probability 1/4 just by measuring them with a detector, equally coupled to the qubits. This happens in the case of repeated strong ~projective! measurements as well as in a more realistic case of weak continuous measurement. In the latter case, the entangled state can be ident...

In the next few months the KLOE-2 detector is expected to start data taking at the upgraded DAφ NE φ-factory of INFN Laboratori Nazionali di Frascati. It aims to collect 20 fb −1 at the φ (1020) peak. We review the status of the upgrades on the detector system.

This paper discusses an approach for continuous and low-power sensing of infrequent, high consequence events. The envisioned sub-10 nW power consumption architecture includes an RF detector, an array of MEMS resonators, and an IC detector. This paper focuses on the MEMS resonator array. We show that MEMS resonators with the Quality factor on the order of 1M can solve the challenging problem of ...

We demonstrate polarization-dependent photo-response enhancement in metamaterial-coupled quantum dots-in-a-well infrared detectors. A gold split-ring resonator metamaterial layer was patterned by electronbeam lithography in the detector aperture. In this integrated structure, the detector spectral response is given by the convolution of the metamaterial field enhancement and the original detect...

The Earth matter effects on supernova (SN) neutrinos can be identified at a single detector through peaks in the Fourier transform of their “inverse energy” spectrum. The positions of these peaks are independent of the SN models and therefore the peaks can be used as a robust signature of the Earth matter effects, which in turn can distinguish between different neutrino mixing scenarios. Wherea...

This paper presents a fast received signal strength indicator (RSSI) circuit for wireless communication application. The proposed circuit is developed using power detectors and an analog-to-digital converter to achieve a fast settling time. The power detector is consisted of a novel logarithmic variable gain amplifier (VGA), a peak detector, and a comparator in a closed loop. The VGA achieved a...

  ABSTRACT   Background : The application of DU emanation for first time contaminated certain areas in the south west region of Iraq after the second Gulf war (1991). These contaminated areas were discovered in 1994. Radioactive contamination was detected using the nuclear enterprise PCM5/1 in soil samples collected from two regions near by grazing lands. This study was done for assessment of D...

Objective(s): The energy resolution of a cadmium-zinc-telluride (CZT) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional Anger type detector which is 10%. Also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. In this study, we used a semiconductor detector and examined the ef...
