摘要: A background self-calibration technique is proposed that can correct both linear and nonlinear errors in the interstage amplifiers of pipeline algorithmic analog-to-digital converters (ADCs). Stage redundancy a architecture exploited to measure gain are corrected using digital post-processing. The allows faster convergence has less dependence on input signal statistics than similar described by Murmann Boser. Simulation results presented for 12-bit pipelined ADC architecture, Boser, nonideal residue amplifiers. With calibration, simulations show signal-to-noise-and-distortion-ratio performance 72 dB spurious-free dynamic range 112 dB, with calibration tracking time constants approximately 8/spl times/10/sup 5/ sample periods, which over ten times reported Boser at level.
