Patent DE 10 2011 113 421
Method for automatic topology modification in the design of analogue integrated circuits
The invention relates to a method for automatic topology modification in the design of analogue, in particular integrated circuits for optimising the transmission behaviour and the stability properties on the basis of systematic eigenvalue shifts with particular consideration of the frequency behaviour and the stability of the respective circuit as well as the pole and zero positions relevant for this.
According to the invention, new network elements, in particular capacitances, are added to the output circuit design with computer support between all independent circuit nodes, whereby the quantity of inserted network elements is weighted and sorted in several steps in order to extract those elements which lead to a permanent improvement in the circuit performance and which are associated with a minimum chip area requirement, whereby a parametric pole-zero analysis is carried out for each inserted network element or a gradient-based eigenvalue optimisation is carried out.
