1.36 Simple Gummel Plot: Evaluation of Gummel characteristics (Vce=const)
(A.01.10)
[Supported Analyzer]
B1500A, 4155B, 4155C, 4156B, 4156C
[Application]
This application evaluates the Gummel characteristics of a NPN BJT with three terminals.
[Device Measured]
Single NPN device with three terminals.
[Parameter Setting]
Test parameters are specified for NPN device under test.
[Description of Measurement]
Base and Collector voltage, referenced to emitter voltage (0 V), sweeps synchronously in accordance with the
test parameter setting.
Currents flowing in base and collector terminals are measured while the synchronized voltages sweep.
[Plot Display]
Collector and base currents in log scale, as well as the current amplification factor (Beta) in linear scale, are
plotted versus base voltage on the linear horizontal axis.
