A novel approach for calculation of component tolerance in analog VLSI circuits using ISFG technique

In this paper we proposed a new approach for calculation of component tolerance which is based on signal flow graph (SFG). This technique is very simple and efficient which is applicable to various types of analog VLSI circuits. In this paper we use back-tracing using inverted signal flow graph (ISFG) which help us to calculate the tolerance of component. Here we applied this approach to two benchmark circuit. First is integrator circuit and second in multi input multi output circuit (MIMO). The calculation and implementation of model for this approach is done with the help of MATLAB/Simulink tool.
