The Medipix/Timepix device consists of a semiconductor detector chip (usually silicon) bonded to a readout chip. The detector chip is equipped with a single common backside electrode and a front side matrix of electrodes (256 x 256 square pixels with pitch of 55 µm) bump bonded to Medipix/Timepix read-out chip.
A significant advantage of these pixel detectors is the possibility of direct...

Peak detectors (peak-detect-and-hold circuits, PDHs) are a key element in nuclear electronics signal processing and have been incorporated as a fully integrated block in several front-end readout chips.
The passive type PDH using diode has very simple structure and high energy efficiency. Though the virtues of a diode PDH, it is not easily employed because of the loss and the distortion of...

Hybrid Pixel Array Detectors (HPAD) are revolutionizing the field of photon detection at synchrotron storage ring and free-electron laser light sources. Excellent detection quantum efficiency, high throughput and noise performance are major improvements over current detectors based on charge coupled device (CCD) cameras. Examples of HPAD detectors are Pilatus, Medipix and XPAD.

The semiconductor pixel detector Timepix contains an array of 256 × 256 square pixels with pitch of 55 µm. The single quantum counting detector Timepix can provide also energy or time information in each pixel. This device is a powerful tool for radiation imaging and ionizing particle tracking. The Timepix device can be read-out via serial or parallel interface enabling speed of 100 fps or...

The analog signal from the sensor of hybrid pixel detectors is hindered by electro-magnetic interference. A systematic diagnostics of induced and common electro-magnetic coupling between the analog part and digital part of these devices is required.
An influence of electro-magnetic interference on a detector precision was observed on the setup of a pixel particle detector and a read-out...

The data acquisition (DAQ) system was designed to capture incoming data at a rate of 25.2 Gbit/s per half-module and send them to a storage system over standard Ethernet connections. It consists mainly of a customizable front-end board (FEB) for data preprocessing and a back-end board for buffering up to 8 Gbyte of data before transmitting them to the storage system. Small form-factor...

Many experiments and applications demand high-resolution, fast waveform digitizing. The use of a switched capacitor array (SCA), as employed by the DRS4 Application Specific Integrated Circuit (ASIC), offers significant cost and power reduction compared to a traditional flash analog-to-digital converter (ADC). The WaveDREAM data acquisition system, based on the DRS4 ASIC, allows continuous...

The so called Time over Threshold mode of the semiconductor pixel detector Timepix allows direct measurement of the deposited energy in each pixel. The Timepix is thus well suited for measurements where the precise position and energetic information are required. The Time over Threshold measurements requires energetic calibration of each pixel. The energetic calibration procedure of the pixels...

In this study, we designed and fabricated active pixel sensors with various photodiode structures using 0.18 μm 1Poly/4Metal CMOS process. All photodiodes have 50 μm pitch for X-ray imaging and the same pixel structure, 3-transistor active pixel. First of all, we considered three basic photodiode structures, n-well/p-epi, n+/p-epi and p+/n-well/p-epi, available in the standard CMOS process. A...

Equivalent noise charge (ENC) is useful method for indicating total noise of detection system [1]. Here, the quantity of ENC depends on aspect ratio of a transistor which places on the input of the preamplifier. Analyzed ENC is use to minimize system noise in designing CMOS readout circuits in the gamma-ray detection system. The analysis in [1] is quietly effective to design CMOS readout...
