The invention provides a time relaxation-intertwined zeroing dynamic element matching encoder, which is characterized by comprising a clock module, an input module, a dynamic element matching encoder, a pseudo-random number generator, and an N-bit either-or multichannel selector, wherein the clock module is used for providing a clock signal; the input module is used for inputting an n-bit binary number B to the dynamic element matching encoder, and B=BnBn-1...B2B1, and B is no less than 0 but no more than 2n-1; the dynamic element matching encoder is used for generating an N-bit binary number D according to the clock signal and the n-bit binary number B, D=DNDN-1...D2D1, N=2n, D1+D2+...+DN=B, and DN=O; the pseudo-random number generator is used for generating an N-bit binary number R according to the clock signal, R=RNRN-1...R2R1, and R1+R2+...+RN=N/2; and the N-bit either-or multichannel selector is respectively connected with the clock module, the dynamic element matching encoder and the pseudo-random number generator for receiving R and D and generating a binary number P and a binary number Q according to R and D, P=PNPN-1...P2P1, and Q=QNQN-1...Q2Q1. The time relaxation-intertwined zeroing dynamic element matching encoder has the advantages of simple structure, high randomization degree and good dynamic features.
