Computer simulation of circuit performance using
SPICE is often useful when analyzing the
performance of analog circuits and systems. This is
particularly true for video and RF-amplifier circuits
where parasitic capacitance and inductance can have
a major effect on circuit performance. A SPICE model
for the THS3111 is available through the Texas
Instruments web site (www.ti.com). The product
information center (PIC) is also available for design
assistance and detailed product information. These
models do a good job of predicting small-signal ac
and transient performance under a wide variety of
operating conditions. They are not intended to model
the distortion characteristics of the amplifier, nor do
they attempt to distinguish between the package
types in their small-signal ac performance. Detailed
information about what is and is not modeled is
contained in the model file itself.
