KASCADE-Grande is a ground based multi-detector experiment measuring extensive air showers in order to study the primary cosmic ray energy spectrum in the energy range from 10 eV to 10 eV. A Flash-ADC based data acquisition system in KASCADE-Grande allows to study the temporal structure of extensive air showers. Muons in extensive air showers are thought to arrive on average earlier than the pa...
A flash analog-to-digital (FADC) based data acquisition system has been designed for the HiRes Fly's Eye detector. A prototype system has been constructed and installed on a single mirror at Dugway, Utah. The trigger sensitivity of the system has been measured using laser shots fired from up to 20 km away. We present the preliminary results of this measurement.
Design and performance of an ultrafast 8bit 0.25 m CMOS flash ADC based on the thresholding inverter comparator are presented.
This paper describes flash ADC design using linearity improved threshold quantized comparator. Here, the need for a reference voltage generation network has been eliminated in a 4 bit flash ADC; with completely digital cell based comparators. Output generated from comparator called thermometer code is related mathematically with binary conversion. This conversion property is used for mathematic...
A novel low-power kick-back reduced comparator for use in high-speed flash analog-to-digital converters (ADC) is presented. The proposed comparator combines cascode transistors to reduce the kick-back noise with a built-in threshold voltage to remove the static power consumption of a reference. Without degrading other figures, the kick-back noise is reduced by a factor 8, compared to a previous...
In this paper, we present a generalized approach for the construction of ripple-flash ADC architectures that consist of cascade-connected capacitive threshold gates, realized using conventional CMOS technology. The main advantages of the proposed ADC architecture are the very small layout area, simple operation, high input-tooutput response speed, and very low power dissipation. A new different...
Progress of roles and schemes of calibration techniques in data converters are reviewed. Correction techniques of matching error and nonlinearity in analog circuits have been developed by digital assist using high-density and low-power digital circuits. The roles of the calibration are not only to improve accuracy but also to reduce power dissipation and chip area. Among various calibration sch...
