Opis:
Time-interleaved analog-to-digital converter (ADC) architecture is crucial to increase the maximum sample rate. However, offset mismatch, gain mismatch, and timing error between time-interleaved channels degrade the performance of time-interleaved ADCs. This paper focuses on the gain mismatch and timing error. Techniques based on Discrete Fourier Transform (DFT) for estimating and correcting gain mismatch and timing error in an M-channel ADC are depicted. Numerical simulations are used to verify the proposed estimation and correction algorithm.

Opis:
The Histogram Test method is a popular technique in analog-to-digital converter (ADC) testing. The presence of additive noise in the test setup or in the ADC itself can potentially affect the accuracy of the test results. In this study, we demonstrate that additive noise causes a bias in the terminal based estimation of the gain but not in the estimation of the offset. The estimation error is determined analytically as a function of the sinusoidal stimulus signal amplitude and the noise standard deviation. We derive an exact but computationally difficult expression as well as a simpler closed form approximation that provides an upper bound of the bias of the terminal based gain. The estimators are validated numerically using a Monte Carlo procedure with simulated and experimental data.

Opis:
A novel design of a circuit used for NTC thermistor linearization is proposed. The novelty of the proposed design consists in a specific combination of two linearization circuits, a serial-parallel resistive voltage divider and a two-stage piecewise linear analog-to-digital converter. At the output of the first linearization circuit the quasi-linear voltage is obtained. To remove the residual voltage nonlinearity, the second linearization circuit, i.e., a two-stage piecewise linear analog-to-digital converter is employed. This circuit is composed of two flash analog-to-digital converters. The first analog-to-digital converter is piecewise linear and it is actually performing the linearization, while the second analog-to-digital converter is linear and it is performing the reduction of the quantization error introduced by the first converter. After the linearization is performed, the maximal absolute value of a difference between the measured and real temperatures is 0.014°C for the temperature range between - 25 and 75°C, and 0.001°C for the temperature range between 10 and 40°C.

Opis:
Free Electron Laser in Hamburg (FLASH) and X-Ray Free Electron Laser (XFEL) are linear accelerators that require a complex and accurate Low Level Radio Frequency (LLRF) control system. Currently working systems are based on aged Versa Module Eurocard (VME) architecture. One of the alternatives for the VME bus is the Advanced Telecommunications and Computing Architecture (ATCA) standard. The ATCA based LLRF controller mainly consists of a few ATCA carrier boards and several Advanced Mezzanine Cards (AMC). AMC modules are available in variety of functions such as: ADC, DAC, data storage, data links and even CPU cards. This paper focuses on the software that allows user to collect and plot the data from commercially available TAMC900 board.

W pracy zaprezentowano projekt scalonego przetwornika analogowo-cyfrowego wykonany w technologii UMC CMOS 180nm. Przedstawiono rozwiązanie pozwalające na znaczące zmniejszenie powierzchni zajmowanej przez układ poprzez dodanie pomocniczego przetwornika C/A. Zostało przybliżone także zagadnienie odpowiedniego doboru kluczy w układach z przełączanymi pojemnościami.

The dynamic progress in the domain of applications involving X rays demands more sophisticated circuits for acquisition and processing of signals from the silicon detectors. This paper presents a design of an integrated analog-to-digital converter dedicated to multichannel silicon detector readout circuits. The successive approximation with charge redistribution architecture was proposed. In order to reduce the total chip area, the DAC was split into two blocks. The capacitor array used as a primary DAC and also as a sampling circuit. As a secondary DAC, the resistive voltage divider was introduced. This solution allowed reducing the total DAC area by the factor of 6, maintaining the same output voltage accuracy. The CMOS switches are described in detail, as they play important role in the switch capacitor circuits, affecting both the speed and accuracy of the primary capacitive DAC. A synchronous regenerative latch is used as a comparator. The ADC is implemented in UMC CMOS 180nm technology. The designed ADC is able to achieve conversion rates of 3 MS/s at 225 žW. The final simulation results show also low nonlinearity of the presented circuit.

Opis:
The authors update the issue disassembly-free control and correction of all components of the error of measuring channels with multi-bit analog-to-digital converters (ADCs). The main disadvantages of existing methods for automatic control of the parameters of multi-bit ADCs, in particular their nonlinearity, are identified. Methods for minimizing instrumental errors and errors caused by limited internal resistances of closed switches, input and output resistances of active elements are investigated. The structures of devices for determining the multiplicative and nonlinear components of the error of multi-bit ADCs based on resistive dividers built on single-nominal resistors are proposed and analyzed. The authors propose a method for the correction of additive, multiplicative and nonlinear components of the error at each of the specified points of the conversion range during non-disassembly control of the ADC with both types of inputs. The possibility of non-disassembly control, as well as correction of multiplicative and nonlinear components of the error of multi-bit ADCs in the entire range of conversion during their on-site control is proven. ADC error correction procedures are proposed. These procedures are practically invariant to the non-informative parameters of active structures with resistive dividers composed of single-nominal resistors. In the article the prospects of practical implementation of the method of error correction during non-dismantling control of ADC parameters using the possibilities provided by modern microelectronic components are shown. The ways to minimize errors are proposed and the requirements to the choice of element parameters for the implementation of the proposed technical solutions are given. It is proved that the proposed structure can be used for non-disassembly control of multiplicative and nonlinear components of the error of precision instrumentation amplifiers.
