A sigma-delta circuit with time sharing architecture includes a coefficient generation element, a sigma-delta processing element, and a storage element. The coefficient generation element is used for generating coefficients for sigma-delta operations. The sigma-delta processing element is used for executing sigma-delta operations according to the coefficients generated by the coefficient generation element. The storage element is used for storing results of the sigma-delta operations executed by the sigma-delta processing element. The sigma-delta circuit is used for executing a plurality of orders of sigma-delta operations through the coefficient generation element, the sigma-delta processing element and the storage element.
