Abstract: Analyzes the working principles of calculating digital calibration of pipelined ADC and the specific features of the implementation circuit.To solve the problem of online renewing digital calibration ratio, a dynamic reconfigurable circuit is designed for the digital domain of pipelined ADC, based on the PipeRench structure and the Multi-context Approach.The architecture has been simulated and the result illustrate that it is capable of actualizing dynamic reconfigurable the digital domain of the pipelined ADC.
