IEEE Transactions on Instrumentation and Measurement, 1996
The paper deals with a neural network-based approach for A/D converter (ADC) modeling. This approach is initially developed with reference to an ADC mathematical model, allowing the neural modeling to be properly setup. Subsequently, a neural model of a real ADC is identified and validated, highlighting the performance of the proposed approach in terms

Evaluation of ADC Testing Systems Using ADC Transfer Standard
IEEE Transactions on Instrumentation and Measurement, 2004A transportable high stable reference AD device was designed and built for a comparison of systems for testing of the dynamic quality of ADCs or modules. Three different input modules enable its use in the frequency range up to 5 MHz. First, this paper refers to the results of the AD device application in the frequency range of the testing signal up to

Proceedings of the IEEE 2013 Custom Integrated Circuits Conference, 2013
Oversampled ADC's are steadily reaching higher effective bandwidths and resolutions at lower power dissipation levels through the use of clever design techniques. The use of continuous time architecture enhances the system level usability by reducing the need for anti-aliasing filters.

MESO-ADC: The ADC design using MESO device
Microelectronics Journal, 2021Abstract In this paper, we propose a new 3-bit ADC based on magnetoelectric spin–orbit (MESO) device. By adjusting the thickness of the magnetoelectric part of MESOs, the ADC possesses multiple switching thresholds for converting input voltages into magnetization state.

Measurement, 1999
The present paper begins by highlighting some difficulties encountered in the application of the testing algorithms described in the recent IEEE Std. 1241 DRAFT to commercial ADCs designed for audio application. In the experienced case study, the inaccurate knowledge of the DUT sampling rate made it unusable in the aforementioned testing algorithms ...

Sub-ADC Architectures for Time-interleaved ADCs
2011Chapter 3 discusses the architecture of the sub-ADCs, which are used in the time-interleaved ADC. A Successive Approximation ADC (SA-ADC) can have a very good power efficiency, its sample-rate is however limited. In a conventional SA-ADC, the sample-rate is mainly limited by settling of the DAC. Overrange techniques can reduce the required DAC settling

“Split ADC” Background Linearization of VCO-Based ADCs
IEEE Transactions on Circuits and Systems I: Regular Papers, 2015A lookup-table digital correction technique using “split ADC” calibration is used for linearization of VCO-based ADCs. Simulation results in a 45 nm CMOS process targeting 10 b and 12 b resolutions show ENOB of 9.58 b and 11.5 b, with convergence times for background calibration adaptation of 380 ms and 5.7 s, respectively. The background LMS procedure

Asthma Device Calibrator (ADC)
2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019Spirometer testing is considered the most common method used to evaluate the pulmonary system. It diagnoses asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing. Nowadays many pharmaceutical companies produce spirometer devices for patients with asthma, designed for home use. However, the machines are replaced

Unified ADC nonlinearity error model for SAR ADC
Measurement, 2008Abstract The paper introduces a new ADC static nonlinearity model focusing on SAR ADC which is labelled the unified ADC nonlinearity error model. The model can also cover any other ADC architectures that have stochastic and/or periodic extremes in their integral nonlinearity function superposed on a “slowly changing” background. In the proposed model
