摘要: The invention relates to an inter-stage gain calibration in a double conversion analog-to-digital converter. Various background techniques calibrate gain, e.g., pipelinedADCs, are described allow open loop amplifier circuits be used as residue amplifiers for better power efficiency. Using various techniques, well-controlled perturbation can injected between two conversions and the actual after measured. By comparing measurement against expected value, information of estimated then applied.
