cvsweep test description

As described in

Simultaneous C-V sweep

(on page D-15), the cvsweep UTM uses the

SIMCVsweep82 user module to make simultaneous C-V measurements. A 595 quasistatic

measurement is a two-step process that requires at least two charge measurements. As shown in the

figure below, charge measurements on two steps are made to yield a single quasistatic reading. The

590 makes a capacitance measurement on every second step of the staircase sweep.
