3.7 Concluding Remarks

MINIMOS-NT has been equipped with a set of capabilities which allows the user to efficiently extract various small-signal quantitities. The implemented small-signal simulation mode can be applied to

• perturb the device with an arbitrary complex-valued sinusoidal input at any terminal,
  
• extract important figures of merit such as the cut-off frequency $f_\textrm {T}$,
  
• obtain the complete intrinsic admittance and scattering matrix of the device,
  
• calculate other commonly used two-port parameter sets,
  
• transform the intrinsic matrices to extrinsic ones,
  
• simulate circuits using the small-signal mixed-mode capabilities,
  
• make further calculations by using the convenient and powerful output and input-deck functions.

The implemented simulator features have been successfully applied for various simulations as discussed in detail in Chapter 6. Since the method requires capabilities for assembling and solving complex-valued linear equation systems, these problems will be discussed in the following two chapters.
