A Theoretically Sound Approach to Analog Circuit Sizing

다국어 초록 (Multilingual Abstract)

We consider the problem of determining the sizes of electrical components in analog circuits, such as operational amplifiers, that maximize a primary performance measure while satisfying some conditions on secondary performance measures. We propose a method that uses a circuit simulator, such as SPICE, to evaluate the performance measures exactly and updates the sizes of the electrical components iteratively using an optimization procedure, which is a variant of the Lagrangian method. The proposed approach guarantees convergence to a local optimal solution under mild conditions. Numerical results demonstrate that the proposed method finds optimal sizes successfully in various circuits including one-stage and two-stage operational amplifiers, a voltage-controlled oscillator, and an inverter chain.
