WebAn on-chip all-digital foreground weights calibration technique integrat-ing self-calibration weight measurement with PN port auto-balance technique is designed to improve the performance and lower the costs of the developed SAR ADC. The SAR ADC has a chip area of 2.7 × 2.4 mm2, and consumes only 100 μW at the 2.5 V supply voltage with 100 KSPS. Self-calibration, sometimes called internal calibration, attempts to characterize and compensate for the offset and gain errors of the internal blocks of the ADC. For example, with a delta-sigma (ΔΣ) ADC that has an integrated PGA (programmable gain amplifier), a self-calibration removes the DC errors from both … See more Some ADCs support calibration modes which can simplify design and help us save some central processing unit (CPU)cycles from the system processor. In this case, you only … See more Below, Table 1, is an excerpt from the AD7124-4 datasheet. Before applying offset calibration, the ADC offset is ±15 μV. However, after the offset calibration, the offset error is in … See more Consider the 3-wire, ratiometric RTD measurement system in Figure 6.
