This paper presents a digitally calibrated 12bit 12.5-MS/s successive-approximation-register (SAR) analog-to-digital converter (ADC) intended for low-power wireless communication and medical instrumentation. The performance of the proposed prototype is enhanced by two techniques. A power saving strategy is proposed. Also, several foreground calibration methods for SAR ADCs are proposed to reduce the...
To improve the tracking accuracy of an underwater maneuvering target, according to its characteristics of low speed and weak maneuvering performance, an adaptive Kalman filter is given based on the online estimation of the process noise variance. As the main filter analyzes the target motion, the process noise variance of the main filter is estimated by an auxiliary filter for being adaptively adjusted...
In order to eliminate the musical noise remained in the results enhanced by short-time spectral attenuation techniques, this paper proposes a novel a priori SNR estimator. The proposed estimator is built on Burg-based power spectral estimation, which takes into account the properties in estimator of smoothness, accuracy and resolution, with the emphasis on their relationships and influences on de-noising...
