Abstract：
The invention provides a sampling and quantification circuit used for a compression sampling analog-to-digital converter and belongs to the field of mixed signal integration circuit design technology. According to the invention, a signal processing procedure including signal observation, error estimation, signal calibration and signal restoration for error correction and a sampling and quantification circuit realization structure with multi-way parallel sampling, simulation domain integration and signal quantization device quantification are provided. The sampling and quantification circuit realization structure successively inputs all simulation sampling and integration results into the same quantification device, so a mismatching problem in a multi-way quantification process is effectively reduced; complexity in realization of a compression sampling analog-to-digital converter system is reduced; and the sampling and quantification circuit is designed with modules, so independence and universality of designing of all modules are improved.
