Abstract:

Based on the algorithm of DSP deducting slope, we designed a new type of alternate integrator. This new integrator makes use of DSP for logic control to make two analog integrator work by turn, and this will reduce integration time of two integrator, which effectively overcome the errors caused by capacitance and temperature drift, thus the signal integration for a long time is realized. At the same time, we also use fixed-point processor Iqmath library functions to achieve real-time compute to improve the precision, it is convenient to achieve integration of real-time and accurate processing.

Key words: Alternant integrator, Drift, Compensation
