A new approach for steady-state analysis of the circuits with strong nonliniarities [articol]

Abstract

The paper presents a new version of the generalised hybrid method for the analysis of the analog circuits with strong nonlinearities, driven by signals with widely separated frequencies. The key idea is to formulate the circuit equations by using multiple time variables, which enable an efficient representation of this kind of signals. Using multiple time-scale the differential algebraic equations (DAE) describing the nonlinear analog circuits are transformed into multitime partial differential equations (MPDE). An illustrative example is presented.
