VAZQUEZ-LEAL, H. et al. Perturbation method applied to a basic diode circuit. []. , 61, 1, pp.69-73. ISSN 0035-001X.

^len^aBecause of the exponential characteristic of silicon diodes, exact solutions cannot be established when operating point and transient analysis are computed. To overcome that problem, the present work proposes a perturbation method which allows obtaining approximated analytic expressions of diode-based circuits. Simulation results show that numerical solutions obtained by using the proposed method are similar to those reported in literature, with the advantage of not requiring a user-selected arbitrary expansion point. Additionally, the method does not use the Lambert function W, reducing the proposed solution complexity, which makes it suitable for engineering applications.
