Accurate Testing of Analog-to-Digital Converters Using Low Linearity Signals With Stimulus Error Identification and Removal

Linearity Testing of Precision Analog-to-Digital Converters Using Stationary Nonlinear Inputs

As the performance of Analog-to-Digital Converters continues to improve, it is becoming more challenging and costly to develop sufficiently fast and low-drift signal generators that are adequately more linear than the ADC for the purpose of linearity testing. This work relaxes the linearity requirements on the signal generators used for ADC testing by alternatively employing multiple non-linear...

Measurement of sampling jitter in analog-to-digital and digital-to-analog converters using analytic signals

A method of sampling jitter measurement based on time-domain analytic signals is proposed. Computer simulations and actual measurements were performed to compare the proposed method with the conventional method, in which jitter is evaluated from the amplitudes of sideband spectra for observed signals in the frequency domain. The results show that the proposed method is effective in that it 1) p...

Signature Testing of Analog-to-digital Converters

− When testing an analog-to-digital converter (ADC) by automatic test equipment (ATE), the latter is capable of performing extensive processing of output responses of the ADC. This allows detection of virtually any fault. However, the cost of ATE is quite high. As well, the external bandwidth of ATE is normally lower than the internal bandwidth of the ADC being tested, which makes it difficult ...

System for Testing Analog-to-Digital Converters

This paper presents a system named ADC TEST that estimates the static and dynamic parameters of an analog-to-digital converter according to the definitions given in IEEE Standard 1241. One shows the available output graphical pages with theirs information and facilities in a practical testing application.
