Abstract :
The paper proposes a new numerical formulation of the classic p-n junction model which is particularly suitable for harmonic-balance applications. Making use of a state-variable approach and of a non conventional choice of the state variable, the numerical difficulties related to the highly nonlinear junction equations are completely waived, and a well-conditioned, fast-converging Newton iteration is obtained in all cases.
