Abstract — An all-digital phase-locked loop (ADPLL) was implemented in 180 nm CMOS technology. The proposed ADPLL uses a novel digitally controlled oscillator to achieve 1 ps resolution. The pure digital phase locked loop is attractive because it is less sensitive to noise and operating conditions than its analog counterpart. The proposed ADPLL can be easily ported to different process as a...

The development architecture of a multichannel data-driven ASIC is presented. It provides the selection of useful events at an early stage of reading out detector signals.
The architecture is based on fast cross-point switches of analog signals, followed by their digitization by a limited set of ADCs and high-speed output data serialization. Such approach reduces the number of subsequent...

Results of developing of a gamma-ray detector based on LaBr3(Ce) scintillation crystal for neutron capture therapy are presented. A energy resolution of the detector measured by photomultiplier tube Hamamatsu R6233-100 is showed. It was 2,9% for gamma line 662 keV from a source 137Cs. For radiative capture gamma line of isotope 10В (478 keV) and annihilation line (511 keV) the value...

In the large-scale high energy physics and astrophysics experiments multi-channel read-out application specific integrated circuits (ASICs) are widely used. The ASICs for such experiments is a complicated system, which usually includes both analog and digital building blocks. A trend to a complication of the system architecture, increase of the channels and building blocks amount in the chip...

The paper describes the read-out ASIC for silicon X-ray drift detectors. The ASIC has been designed in CMOS 0.35 um technology and contained two read-out channels. Each channel include preamplifier and shaper. Preamplifiers optimized for operation with detectors, having capacitances of 100 fF. The 6-th order shaper have a controllable time constants (0.5 – 8 us).
