Abstract :
The paper presents a new version of the generalized hybrid method for the steady-state analysis of the analog circuits with strong nonlinearities, driven by signals with widely separated frequencies. The key idea is to formulate the circuit hybrid equations by using for signal representation multiple time-scales, which transform the differential algebraic equations (DAEs) describing the nonlinear analog circuits into multi-time partial differential equations (MPDEs). An illustrative example is presented.
