Details
The module measures quasistatic capacitance and leakage current as a function of delay time using
the 595. It is used to determine the equilibrium condition. Each quasistatic capacitance reading is
calculated from charge measurements performed on every two steps of a voltage sweep. Leakage
current at the end of each reading sample is also calculated (i = ∆Q/∆t).
The following figure shows the default parameters for the QTsweep82 user module.
