Abstract :
This paper presents a new method to perform efficient analog circuit synthesis by using accurate multiparameter sensitivity analysis based on element-coefficient diagrams (ECDs). An ECD is the cancellation-free and per-coefficient term generation version of determinant decision diagrams (DDDs). The techniques based on DDD are the fastest symbolic analysis algorithms reported so far in literature. The symbolic multiparameter sensitivity equations obtained from ECDs can be evaluated so as to tune the parameters in analog synthesis process efficiently. The proposed methodology has been applied for the synthesis of a two stage opamp circuit. The experimental results demonstrate that the speed and convergence of analog synthesis are improved significantly.
