Adaptive method for estimating the inl in analog-to-digital converters (adcs)
, 2009 [EN] The invention relates to a low-cost digital method for estimating the integral non-linearity (INL) in analog-todigital converters. Said method is valid for the testing and characterisation of any analog-to-digital conversion topology in both concurrent and non-concurrent built-in self-test BIST applications.

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1017-1029, February 2026.Abstract Purpose Using parallel transmission (pTx) in ultra‐high field MRI allows efficient radiofrequency pulse designs that can produce uniform excitations. Here, we demonstrate that pTx can simultaneously mitigate B1+$$ {\mathrm{B}}_1^{+} $$ non‐uniformity and off‐resonance artifacts in balanced steady‐state free precession sequences at 7 T.

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1044-1067, February 2026.Abstract Purpose Lower field strength scanners with large bore size or complex geometries, and scanners with stronger gradient systems experience increased gradient nonlinearity and concomitant fields, each of which causes distortions in EPI. Current correction approaches based on image‐domain interpolation introduce undesirable spatial blurring.

Design of a 6-bit Threshold Inverter Quantization (TIQ) Flash Analog to Digital Converter (ADC)
An ADC is used to convert analog signals into binary signals. Compared with many other types of ADCs, flash converters are incredibly quick. A typical Flash ADC consists of 2n resistors, 2n-1 op-amp comparators, and an encoder which requires more area.
