APPLICATIONS INFORMATION

MAT03 MODELS

zenering of the base-emitter junctions.

The analysis programs, SPICE and SABER, are primarily used

in evaluating the functional performance of systems. The models

are provided only as an aid in using these simulation programs.

MAT03 NOISE MEASUREMENT

√R nV/√Hz, where R is in kΩ) and semiconductor

junctions (shot noise, caused by current flowing through a

junction, produces voltage noise in series impedances such as

√I pA/√Hz where

I is in

µA) contribute to the system input noise.

Figure 2 illustrates a technique for measuring the equivalent in-

put noise voltage of the MAT03. 1 mA of stage current is used
