中文摘要	A novel capacitor mismatch calibration technique for pipelined analog-to-digital conversion is presented. The nonlinear capacitor mismatch error is reduced to the second order through an algorithmic circuit method, involving charge summing, capacitors exchange,and charge redistribution. A 13b, 2M sample/s pipelined A/D converter implemented in 0.6 mu m CMOS technology has been designed to verify the proposed technique. Measured performance includes 0.5 LSB of DNL, 2.5 LSB of INL, 71. 2 dB of SFDR and 64.1 dB of SNDR for 19. 2 kHz input at 614k sample/s, 70.6 dB of SFDR and 62.22 dB of SNDR for 125 kHz input at 2M sample/s. This result shows that the linearity of the ADC is better than the capacitor matching precision decided by the technology. Thus the adopted capacitor mismatch calibration technique is proved to be effective.
