Abstract: PURPOSE: The continuous-time sigma-delta modulator can reduce the burden which has to increase the peak value of on current by being proceed the charging operation or the electric discharge operation with the capacitors of 2 through one cycle whole. CONSTITUTION: An integrator(200) integrates the difference of the analog signal and the differential-inputted input signal. The analog to digital convertor(220) changes the output of integrator into the digital output signal. The digital analog converter(240) changes the digital output signal into the analog signal. In the first switching route is the discharge section, the analog signal corresponding to the digital output signal is generated. In the first switching route is the filled sphere liver, the reference voltage is stored.
