This paper presents a design and measurements of multichannel integrated circuits in 90 nm CMOS dedicated to readout of hybrid pixels detectors in imaging applications. The chip contains a matrix of 40 × 32 pixels with the size of 100µm × 100µm. Each pixel contains a charge sensitive amplifier, a main amplifier stage, two(More)
The paper presents a highly efficient system for automated wafer testing implemented on a single software platform. Building fully functional device requires often expensive and time consuming, manufacturing steps. Thus, the ASICs on the wafer ought to be tested in advance to ensure that only the chips with no manufacturing defects will be used in the(More)
Multichannel ASIC for digital X-ray imaging requires one or more discriminators in each recording channel. The critical parameters of these discriminators are low power consumption and low offset spreads from channel to channel. In the readout electronics dedicated to work with high rates of input pulses the charge sensitive amplifier, filter stages and(More)
We present the FPGA implementation of the zero dead-time mode operation for the Ultra Fast X-Ray Camera. The camera consists of two UFXC32k chips bump-bonded to a single silicon sensor incorporated in a stand-alone camera communicating with an external system via Ethernet or Camera Link interface. Commercially available controller sbRIO 9651 including Zynq(More)
The Vertically Integrated Photon Imaging Chip (VIPIC) was custom-designed for X-ray photon correlation spectroscopy, an application in which occupancy per pixel is low but high time resolution is needed. VIPIC operates in a sparsified streaming mode in which each detected photon is immediately read out as a time- and position-stamped event. This event(More)
This article describes the advantages of using the Field Programmable Gate Arrays (FPGA) for significant acceleration of Monte Carlo simulations leading to the fast verification of new ideas. An example of a real and challenging problem in the design of application specific integrated circuits (ASIC) for 2D X-ray imaging applications, namely the charge(More)
