1. a conversion circuit of orthogonal sine signal is characterized in that, described change-over circuit comprises SH module (101), comparator (102) and control module (103),Described SH module (101) is sampled to the orthogonal sine signal that receives from the outside and is amplified summation, exports a voltage signal (Vout);

  • Described comparator (102) receives from the voltage signal (Vout) of described SH module (101) output, and exports a comparison signal;

    Described control module (103) receives outside clock signal (clk), and according to the comparison signal that receives from described comparator (102), to described SH module (101) output control signal, make described SH module (101) adjust gain amplifier, and be operated in phase place judgment model or mode changeover signal according to this control signal.
