1. A curve fitting circuit, comprising:

  • n segmentation processing circuits, wherein n is greater than or equal to 2; and

    q first adder circuits, wherein q is a natural number;

    wherein each segmentation processing circuit of the n segmentation processing circuits is configured to;

    receive an input signal;

    intercept a part of the input signal according to a preset rule;

    generate a to-be-processed signal according to the intercepted part; and

    generate q output signals according to the to-be-processed signal using a polynomial fitting method, wherein parts of the input signal intercepted by different segmentation processing circuits are not exactly the same; and

    wherein each first adder circuit is configured to;

    receive one signal in the q output signals of each segmentation processing circuit; and

    obtain one output signal of the curve fitting circuit according to a sum of received n signals, wherein different first adder circuits receive different output signals in q output signals of a same segmentation processing circuit.
