چکیده
In this paper a dynamic behavior model of analog to digital converters is proposed. The model is aimed for post correction in wideband applications. The suggested post correction method is a combination of look up tables and model based correction. The model consists of three components. The first is a component represented by a Hammerstein model; that is a static nonlinearity followed by a time invariant linear filter. The second component is a nonparametric model caused by significant deviation from the characterized integral nonlinearity and the output from the Hammerstein model. The third component contains of the remaining deviation and is considered as a random model error. Results from simulations verify that the examined ADC can be described by an ordinary Hammerstein model and a static look-up table.

In the paper, two approaches to measurements of circuit functions of analog parts of mixed-signal systems controlled by microcontrollers are presented. They base on the utilization of internal resources of the microcontrollers. The first approach uses an analog to digital converter (ADC), an analog comparator and a timer. The second one uses only the ADC and the timer. The measurement procedure...

The main goal of this paper is to characterize the low-frequency part of ADC transfer function by dual tone testing from intermodulation components that are independent of test signal harmonic distortion. The theoretical analyses of incoherently sampled signals in the frequency domain and of intermodulation distortion are provided and the theory is verified by experimental results.

We present here expressions to determine the uncertainty interval of the estimates of transition voltages and code bin widths of an analogue to digital converter obtained with the Standard Histogram Test. We consider the presence of additive noise as it influences the precision and causes a bias on the test results.

In order to identify if a subscriber loop is suitable for DSL service, the transfer function of the loop has to be estimated. Several measurement techniques exist, however Single Ended Line Testing is gaining much attention lately. This method allows only measuring at the central office side and yields a reflectogram. One of the critical issues in the estimation of the transfer function from th...
