This paper presents a design of the built-in high resolution signal generator for testing analog-to-digital converter (ADC) and digital-to-analog converter (DAC). The sigma-delta demodulator scheme is used in the design to generate on-chip high accurate stimulus. We discuss the issues on the...
With a two-step architecture, the accuracy of the coarse ADC needs to be much better than its resolution. In addition to the coarse ADC, the DAC, and the subtractor also play a key role in the accuracy of the residue signal. That’s why the maximum allowed ...

An improved split-capacitive-array digital-to-analogue converter (DAC) with an optimised segmentation degree (i.e. the number of bits in the most significant bit (MSB) sub-array) is proposed to reduce the area, the switching power consumption and improve the linearity compared to a conventional...
