| Abstract | ABSTRACT by Petzold [3] and later used for circuit simulation (e.g., [4, 5, In this paper, we propose a novel envelope-following method which 6, 7, 8]), are time-domain envelope-following methods, in which is uniformly applicable to both non-autonomous and oscillatory only a few selected fast cycles are simulated using transient, while circuits. A key feature of our technique is the use of an efficient the rest are interpolated. Another popular envelope approach is the minimum least squares solution technique to solve an underdeter- frequency-domain Fourier-envelope method [9, 10, 11], which uses mined envelope system directly. This leads to a general purpose a combination of Harmonic balance and time integration methods. approach which is much easier to solve than previous phase condi- Recently, a new class of envelope methods, based on Multi-time tion based envelope-following method, improving numerically ro- Partial Differential Equation (MPDE) circuit formulations [12, 13, bustness dramatically.
