ADCDACladdorinspired
ADCDACladdorinspired is a term used in discussions of mixed-signal circuit design to describe a class of architectures that fuse principles from digital-to-analog converter DAC ladder topologies with analog-to-digital converter ADC processes. The concept envisions arranging a resistor or capacitor ladder, commonly used to generate precise analog references in DACs, within the signal path or calibration loop of an ADC to improve linearity, monotonicity, and calibration efficiency. The term is not widely standardized and appears mainly in theoretical or exploratory design notes rather than as a formal standard.
Conceptually, the approach adapts ladder networks to provide shared references or code-to-analog mapping for ADC segments,
Potential benefits include improved integral nonlinearity (INL) and differential nonlinearity (DNL), better thermal tracking, and simplified
It relates to broader topics such as mixed-signal co-design, time-interleaved ADCs, and digital calibration methods, and
