Martin Clara: Delta sigma patterns for calibrating a digital-to-analog converter. ANALOG DEVICES, Patent Capital Group, February 21, 2017: US09577657 (1 worldwide citation)

A digital to analog converter (DAC) maps a digital word to an analog output. The DAC bits may have amplitude and timing errors. These errors (or sometimes referred herein as “non-idealities”) result in distortion and degradation of the dynamic range in DACs. To reduce these negative effects, delta-s ...

Khiem Quang Nguyen: Envelope-dependent noise-shaped segmentation in oversampling digital-to-analog converters. ANALOG DEVICES, Patent Capital Group, August 15, 2017: US09735799 (1 worldwide citation)

Improved mechanisms for applying noise-shaped segmentation techniques in a multi-bit DAC are disclosed. Noise-shaped segmentation refers to constructing two or more noise-shaped signals whose sum equals the original digital input signal by splitting each word of the input signal into two or more sub ...
