With a total of 3 patents to his name, Arias has demonstrated a commitment to advancing technology through innovative solutions.
Latest Patents
One of Arias's latest patents focuses on the digital correction of nonlinearity errors in multibit delta-sigma digital-to-analog converters. This invention provides a method for estimating the integral nonlinearity (INL) error of multibit ADACs using a low-resolution calibration ADC (CADC). The INL values are stored in a random-access memory (RAM) table and are utilized to compensate for the distortion of the ADAC in the digital domain. By combining this compensation with mismatch-shaping techniques such as DWA, the resolution requirement for the CADC can be significantly relaxed. The implementation of this correction circuit for error-feedback modulators is straightforward, requiring only a digital summation without the need for additional digital filtering.
