Efficient temperature-dependent symbolic sensitivity analysis and symbolic performance evaluation in analog circuit synthesis

ABSTRACT

We present a new methodology for fast analog circuit synthesis, based on the use of temperature-dependent symbolic sensitivity analysis and symbolic performance evaluation in synthesis loop. Fast sensitivity analysis achieved and performance estimation are based on element-coefficient diagrams (ECDs). Sensitivity and performance evaluation expressions are generated from ECDs at the same time which reduces overall runtime greatly. The experimental results demonstrate that the speed and convergence of analog synthesis are improved significantly.
