In this paper, another capacitor mismatch error cancellation tech-nique is proposed in the context of a successive-approximation ADC. In the proposed technique, the first-order error is cancelled at the cost of 50% increase in the conversion time, instead of the two-fold increased described in .
A novel model is proposed to explain the capacitor mismatch induced error, and then two classic calibration techniques, which are called low-to-high (L2H) end and high-to-low (H2L) herein, are also reviewed. With the accurate analysis and the model, we present a calibration technique exemplified in a 12-bit SAR ADC with split-CDAC.
The capacitor error averaging technique proposed in [3, 16, 17] is an effective analog calibration technique. In this technique, calibration can be performed in the background, meaning normal operation is not hindered by calibration.
At the cost of a 50% increase in the conversion time, the first-order capacitor mismatch error is cancelled. Methods for achiev-ing top-plate parasitic insensitive operation are described, and the use of a gain- and offset-compensated opamp is explained.
The proposed calibration circuit recursively amplifies the capacitor mismatch error by re-utilizing a multiplying digital-to-analog converter in a pipeline stage without increasing the circuit complexity, and the amplified error voltage is converted into digital code by utilizing the remaining pipeline stages.
Most errors, except capacitor mismatch error, can be addressed owing to advances in circuit techniques and CMOS technologies [1, 2, 3, 4, 5]. However, capacitor mismatch significantly depends on the CMOS technology and requires special calibration circuitry to minimize the linearity degradation of the ADC output.
