A digital background calibration technique using signal-dependent dithering is proposed to correct the multiplying DAC (MDAC) gain error of a 2.5b/stage pipelined ADC. Behavioral simulation results show that, using the proposed calibration technique, the signal-to-noise-and-distortion ratio improves from 63.3 to 79.3 dB and the spurious-free dynamic range is increased from 63.9 to 96.4 dB after calibrating...
With the development of high building, subway engineering, municipal engineering and underground engineering, the number of deep foundation increases greatly. The failure of the foundation will cause many environment geotechnical problems and accidences, which will threaten the safety of engineering and cause some loss of people's life and economy. The pre-stress nail-pile structure is widely applied...
