“…The device internal capacitances (C ge , C gc , and C ce ) resonate mainly with the device parasitic and PCB track inductances connecting the devices. The gate resistors in the loop should be able to the LHS of the s-plane [17] suppress the oscillations providing their values are big enough. Fig.…”

“…In this case, the mode-in-state participation factors of (22) are the same as those of the linearized systemẋ = Ax.Proof. First, we normalize A using the change of coordinates(24) where V = [r 1 r 2 · · · r n ] represents the matrix of right eigenvectors of A. Under the homeomorophism in the Hartman-Grobman theorem the ODE (22) becomeṡz = Λz(40)The proof regarding mode-in-state participation factors comes directly from applying the result for the linear case in Section 3.…”
