Graph-Based Symbolic Technique and Its Application in the Frequency Response Bound Analysis of Analog Integrated Circuits

Algorithm 4

Calculation of frequency response bounds using our graph-based symbolic technique from Section 2 and constrained optimization.

(1) Parse circuit netlist.

(2) Set bounds on parameters affected by process variations.

(3) Derive the symbolic expression, for example, the transfer function.

(4) for All frequencies 𝜔_𝑖  do

(5)    Constrained optimization to find magnitude bounds on 𝜔_𝑖.
