Abstract The Picosecond Avalanche Detector is a multi-junction silicon pixel detector based on (NP) drift gain structure, devised to enable charged-particle tracking with high spatial resolution and picosecond time-stamp capability. It uses continuous junction deep inside the sensor volume amplify primary charge produced by ionizing radiation in thin absorption layer. signal then induced second...

In this work we report a separate-absorption-charge-multiplication Ge/Si avalanche photodiode with an enhanced gain-bandwidth-product of 845 GHz at a wavelength of 1310 nm. The corresponding gain value is 65 and the electrical bandwidth is 13 GHz at an optical input power of -30 dBm. The unconventional high gain-bandwidth-product is investigated using device physical simulation and optical puls...

Here we report on measurements of optical gain at 1.5 m in crystalline silicon. Gain is achieved by the incorporation of the rare earth erbium in silicon. A method was developed to enable the gain measurement in short silicon waveguides. Crucially, gain values obtained are significantly greater than previously supposed. We have measured a lower limit for the optical cross section for Er3+ of 5 ...

This communication presents the antenna gain pattern estimation from backscattering coefficient measurement performed within a reverberation chamber (RC). The is measured for two load conditions, namely, an open circuit (OC) and 50 $\Omega $ </inline-f...

This paper presents development of passive channel sounder using software defined radio based receivers and commercial transmitter operating in cellular network. Accuracy developed is verified by over-the-air path gain measurement outdoor open space. For evaluation, line-of-sight estimated correlation method compared with theoretical gain.

Abstract: Distributed consensus schemes in the presence of measurement errors are analyzed for both first-order and second-order dynamic agents. The connection between consensus error of coordination variables and the measurement errors is derived. Analytic estimates of consensus error are given. A design problem based on minimizing the “error gain” is thus identified. One simple example illust...
