Hung, L.-H.L.-H.HungTAI-CHENG LEE2020-06-112020-06-11200915497747https://scholars.lib.ntu.edu.tw/handle/123456789/498490A digital background calibration technique is proposed to correct gain errors in pipelined analog-to-digital converters (ADCs). The calibration technique performs the error estimation and the adaptive error correction based on the concept of split ADCs. With the 1- or 1.5-bit realization in pipelined stages, capacitor-mismatch errors can be merged with gain errors, and the proposed calibration technique can be utilized. Behavioral simulations show that the signal-to-noise-and-distortion ratio of a 12-bit pipelined ADC with an 8-bit gain accuracy and the capacitor mismatch σ = 0.125% can be improved from 56.4 to 73.8 dB. The calibration process converges in approximately 200000 cycles. © 2009 IEEE.Adaptive systems; Analog-to-digital conversion; Digital background calibration; Pipelined analog-to-digital converters (ADCs)Adaptive systems; Calibration; Digital to analog conversion; Error correction; Pipelines; Signal to noise ratio; Behavioral simulation; Calibration process; Calibration techniques; Capacitor mismatch; Capacitor mismatch errors; Digital background calibration; Pipelined analog-to-digital converter; Signal to noise and distortion ratio; Analog to digital conversionjournal article10.1109/TCSII.2009.20340772-s2.0-70450225785https://www.scopus.com/inward/record.uri?eid=2-s2.0-70450225785&doi=10.1109%2fTCSII.2009.2034077&partnerID=40&md5=a5e1bdd9160c22be54aaa8758e7bbd2c
