parlib user library

The parlib extracts device parameters on bipolar-junction transistors and MOSFETs. Extracted
parameters include Beta, resistance, threshold voltage, and V
MOSFETs.

Description
Measure beta of bipolar transistor at the specified IE and VCB.
Find data based on an x search or a y search.
Decide if TRIGL or TRIGH should be used.
Returns the value of the body-effect parameter gamma obtained from two
measurements of the threshold voltage at different substrate bias voltages.
Estimate FET conductance (dId/dVg) at V
This test makes measurements that are similiar to the gummel test in the
Demo project for 3-terminal pnp BJTs.
This test makes measurements that are similiar to the ig-vg test in the Demo
project for 4-terminal MOSFETs.
This test makes measurements that are similiar to the vce-ic test in the
Demo project for 3-terminal BJTs.
This test makes measurements that are similiar to the vds-id test in the
Demo project for 4-terminal MOSFETs.
This test makes measurements that are similiar to the vgs-id test in the
Demo project for 4-terminal MOSFETs.
Returns the value of the extrapolated threshold voltage from multiple linear
least square fits to the gate characteristics of a FET in the nonsaturated
region.
OVPControl user library (on page 6-315) allows you to set the maximum
Description
This module is a functional programming reference to
illustrate the basic commands necessary to perform a
pulse I-V (2-level pulse) sweep. It returns voltage and
current spot means for pulse amplitude and base by
doing a voltage amplitude pulse I-V sweep using one
channel of the 4225-PMU.
This module is a functional programming reference to
illustrate the basic commands necessary to perform a
pulse I-V (2-level pulse) sweep with waveform
capture. It captures a voltage amplitude pulse I-V
waveform using one channel of the 4225-PMU. It
returns voltage and current samples versus time for a
single channel.
