The following figure shows the three regions of a typical C-V curve for a MOS capacitor.

Capacitance measurement tests

The 4200A-SCS provides the following user modules to perform C-V tests using the Keysight Models

4284A and 4980A:

CvSweep4284. C-V sweep test: Performs a capacitance and conductance measurement at each

step of a user-configured linear voltage sweep.

Cmeas4284. C measurement: Performs a capacitance and conductance measurement at a fixed

bias voltage.

Details on the user modules for the Keysight Models 4284A and 4980A are provided in the

HP4284ulib User Library Reference

If needed, you can initially do an OPEN and SHORT correction on the 4284A or 4980A to achieve

the most accurate C-V measurements. See the Keysight 4284A or 4980A Operation Manual for

Figure 570: Typical C-V curve for a MOS capacitor

(on page 6-309).
