Figure 1 is a structure of dual-slope integrator. Its measurement cycle has two distinct phases: input signal integration (INT) phase and reference voltage integration (DINT) phase. In INT phase, the input signal is integrated for a fixed time period, then A/D enters DINT phase in which an opposite polarity constant reference voltage is integrated until the integrator output voltage becomes to zero. Since both the time period for input signal integration and the amount of reference voltage are fixed, thus the de-integration time is proportional to the input signal. Hence, we can define the mathematical equation about input signal, reference voltage integration (see Figure 1.): ∫ × × × = × INT T DINT REF IN T V C Buf dt t V C Buf 0 int 1 ) ( int 1 where, ) (t V IN = input signal REF V = reference voltage INT T = integration time (fixed) DINT T = de-integration time (proportional to ) (t V IN ) |
