Abstract : A conductance and capacitance test system was
designed in this paper. AD5933 a new chip for impedance testing was used
in it. By designing the test system, and testing the impedance of a
model, which is a resistor in parallel with a capacitor, under different
frequency (range from1000Hz to 100kHz). The information of impedance,
real part, and imaginary part of the model under the frequency points
were get. Based on this, the internal relations between conductance,
capacitance, impedance, real part and imaginary part were carefully
analyzed, using the soft-sensing method established the capacitance
support vector machine (SVM) regression model on MATLAB. The regression
model is the relation between resistance, impedance and capacitance. The
test results showed that the test relative error is small in the
capacitance range (0.1 pf~33 pf) and the conductance range
(9.05*10-3s~3.8*10-5s), the biggest, smallest and average test error of
capacitance are -2.9%, 0.2%, 1.27% respectively. The study showed that
using AD5933 and the soft-sensing method to realize the multi-parameter
test is feasible.
