TOPAS -
TransistOr PArameter Scaleable model is a high precision non-linear
transistor model for the simulation of any unipolar transistor
structure based upon different material systems such as GaAs, GaN, InP
or even Si LDMOS. Due to the special kind of equivalent element
circuitry small signal circuit elements are optimized without changing
the perfect agreement of static simulations compared to measurements.
The implementation of the model into the common used circuit simulation
software ADS™ of Keysight Technologies is consistent and easy to use. For low input
power a large signal simulation turns into a small signal simulation
without any differences. This behavior is reached, although all
intrinsic equivalent circuit elements are driven by the gate-source
voltage as well as by the drain-source voltage. Due to this control
functionality TOPAS is valid for all bias points. Thus, for different
kinds of applications there is no need for different simulation files.
