This paper presents a comprehensive calibration engine for Pipelined ADCs. Linear, nonlinear, memory errors as well as errors due to the capacitor mismatch in a multi-bit DAC are all estimated and compensated for using background digital calibration techniques. The work also includes a novel approach for correcting nonlinear errors that reduces the digital(More)
Pipeline analog to digital converters are subject to different errors caused by analog circuit imperfections which limit their accuracy. Much work has been done in recent years to compensate for these errors in the digital domain. However, none of them has addressed all possible errors. Only few of them compensate for higher order nonlinearity in pipeline(More)
