Abstract

PURPOSE:To obtain smoothed output, by analogically interpolating a D/A conversion output in a higher frequency than the sampling frequency. CONSTITUTION:A D/A conversion output Vi charges a capacitor 25 via an FET22 which is conductive with a pulse P2 of the 2nd phase. Next, an FET21 is conductive with the pulse P1 of the 1st phase and a capacitor 24 is charged with the Vi. Finally, an FET23 is conductive with the pulse P3 of the 3rd phase, the voltage between the capacitors 24, 25 is averaged to obtain a voltage of (Vi1+Vi2)/2 for the smoothing of the output.
