CV Sweep Measurement
CV Sweep Measurement
Table 4-18 explains example subprogram that performs capacitance-voltage (CV)
sweep measurement. This example measures MOSFET gate-substrate capacitance
by using the multi frequency capacitance measurement unit (MFCMU) and a
SMU/CMU unify unit (SCUU).
To perform the example subprogram shown in Table 4-18, you need the following
setup.
• Insert the following line to the program (at the top of the program).
#include <windows.h>
• Insert the subprograms shown in Table 4-15 and Table 4-16 to the program
(between the check_err subprogram and the perform_meas subprogram).
• phase_compen subprogram
• open_corr subprogram
