7 MixedSignal
7.12 Ic-Vc Vb Mismatch[3]: Ic-Vce characteristics mismatch, Vb sweep, 3-
terminal (A.01.20)
[Supported Analyzer]
B1500A
[Description]
Measures the collector current vs collector voltage (Ic-Ice) characteristics of device A, and measures the Ic-Ice
characteristics of device B. After that, calculates the differences between Ic values by using the following
formula, and plots the results.
Delta_Ic=(Icollector_A-Icollector_B)/Icollector_A*100
[Device Under Test]
Bipolar transistor, 3 terminals, 2 ea.
