摘要：This paper presents the design and the implementation of a standard auto-calibration
system, to correct measurement chain and ensure its accuracy. The adopted solution
consists in designing a reconfigurable instrumentation based on the use of a
programmable analog circuit (FPAA), allowing the automation of various test and
adjustment operations. The measurement chain transfer curve is periodically corrected
using the progressive polynomial calibration method, ensuring systematic correction of
each taken measurement. The hardware/software implementation of the system was
carried out in an embedded configuration based on a FPGA platform. The obtained
results highlight adaptability of the proposed calibration method at various sensors kinds
as well as the implementation simplicity, and shows how the measuring accuracy can be
considerably improved.
