Anotace:
The first part of the subject deals with contemporary models of both classical semiconductor elements (in submicron
domain) and special microwave transistors as HBT, pHEMT etc. Moreover, models of power MOS (LDMOS) transistors
are also defined and characterizing the elements by X-parameters is included as well. The modeling part of the subject is
completed by characterization nano-scale elements, including noise models, and by a description of memristors,
memcapacitors and meminductors.
The second part of the subject contains algorithms for solving nonlinear stiff systems of differential-algebraic equations
in implicit form combined with nonstandard sensitivity analysis in time domain. The sensitivity analysis in the frequency
domain is also included as well as nonstandard sensitivity analysis of noise figure. Attention is also given to steady-state
algorithms, in particular, their more difficult form usable for autonomous circuits. The analytic methods are naturally
complemented by single- and multi-objective optimizations. Up to four-dimensional optimizations are demonstrated on
very complicated, but technically useful tasks from the microwave area including power RF amplifiers.
