chargepumping user library
The
chargepumping
user library contains several user modules to characterize interface and
charge-trapping phenomena. The next table lists and briefly describes the user modules.
chargepumping user modules
User module
Description
AmplitudeSweep
Pulse amplitude is swept while the SMU base voltage is kept constant. The
charge pumping current (I
CP
) is measured as a function of the pulse
amplitude voltage.
AmplitudeSweep_2SMU
Same as the AmplitudeSweep user module, except that it uses a second
SMU to apply a DC bias voltage to the source/drain terminals.
BaseSweep
The base voltage of the waveform is swept by a SMU while the amplitude of
the pulse is kept constant. The resulting charge pumping (I
CP
) is measured
as a function of the base voltage.
BaseSweep_2SMU
Same as BaseSweep user module, except it uses a second SMU to apply a
DC bias voltage to the source/drain terminals.
FallTimeLinearSweep
Performs a linear sweep of the falling transition time of the pulse. Charge
pumping current (ICP) is measured and graphed as a function of the fall
time.
FreqFactorSweep
With the pulse amplitude, offset voltage, and rise/fall time kept constant, the
charge pumping current (ICP) is measured as a function of a multiplier
factor controlled frequency sweep of the test frequency.
FreqLinearSweep
With the pulse amplitude, offset voltage, and rise/fall time kept constant, the
(ICP) is measured as a function of a linear sweep of the test frequency.
RiseTimeLinearSweep
Performs a linear sweep of the rising transition time of the pulse. Charge
pumping (ICP) is measured as a function of the rise time.
cvivulib user library
The
cvivulib
user library contains user modules for configuring the 4200A-CVIV Multi-Switch. The
next table lists and briefly describes the user modules.

Description
cviv_configure
cviv-configure
This user module configures the CVIV relays and
the display for each channel.
cvu_cviv_comp_collect
cvu-cviv-comp-collect
This user module provides CVU compensation
collection for open, short, and load with a 4200A-
CVIV.
