Abstract The concept of piecewise sampling is applied to differential measurement of sine wave voltage. The multi-period strategy is adopted for frequency expansion of sinusoidal voltage under measurement. The experiments demonstrate practical process of these measurements and verify feasibility of the proposed approaches. The characteristic of differential measurement based on staircase waveform is analyzed. For meeting this characteristic a novel concept termed as “limiting amplitude piecewise sampling” is proposed, and the corresponding approach is presented. Based on this approach a suggestion is consequently provided to improve accuracy of the AC quantum voltage standard from level of 10-7 to 10-8. Its principle and detailed method are presented and the necessary conditions are mentioned.
