Section 6: Clarius Model 4200A-SCS Parameter Analyzer Reference Manual6-316 4200A-901-01 Rev. C / February 2017parlib user libraryThe parlib extracts device parameters on bipolar-junction transistors and MOSFETs. Extractedparameters include Beta, resistance, threshold voltage, and V ds-Id sweeps and Vgs-Id sweeps forMOSFETs.parlib user modulesUser module Descriptionbeta Measure beta of bipolar transistor at the specified IE and VCB.fnddat Find data based on an x search or a y search.fndtrg Decide if TRIGL or TRIGH should be used.gamma Returns the value of the body-effect parameter gamma obtained from twomeasurements of the threshold voltage at different substrate bias voltages.gm Estimate FET conductance (dId/dVg) at V ds and V gs.gummel This test makes measurements that are similiar to the gummel test in theDemo project for 3-terminal pnp BJTs.igvg This test makes measurements that are similiar to the ig-vg test in the Demoproject for 4-terminal MOSFETs.vceic This test makes measurements that are similiar to the vce-ic test in theDemo project for 3-terminal BJTs.vdsid This test makes measurements that are similiar to the vds-id test in theDemo project for 4-terminal MOSFETs.vgsid1 This test makes measurements that are similiar to the vgs-id test in theDemo project for 4-terminal MOSFETs.vtext Returns the value of the extrapolated threshold voltage from multiple linearleast square fits to the gate characteristics of a FET in the nonsaturatedregion.PMU_examples_ulib user libraryThe user modules in this library are used in the pmu-dut-examples project.The user module in the OVPControl user library (on page 6-315) allows you to set the maximumvoltage of the SMU.PMU_examples_ulib user modulesUser module DescriptionPMU_1Chan_Sweep_Example This module is a functional programming reference toillustrate the basic commands necessary to perform apulse I-V (2-level pulse) sweep. It returns voltage andcurrent spot means for pulse amplitude and base bydoing a voltage amplitude pulse I-V sweep using onechannel of the 4225-PMU.PMU_1Chan_Waveform_Example This module is a functional programming reference toillustrate the basic commands necessary to perform apulse I-V (2-level pulse) sweep with waveformcapture. It captures a voltage amplitude pulse I-Vwaveform using one channel of the 4225-PMU. Itreturns voltage and current samples versus time for asingle channel.
