Transient behavior of Gunn domains and associated equivalent circuits

A new and more exact expression for the transient behavior of Gunn domains is found. General expressions for lumped-element values for an equivalent circuit are also presented. Some discrepancies between previously developed equivalent circuits are resolved. It is shown that the nonlinear equation describing the domain voltage may be put in the form of Abel´s equation. Limitations in the use of zero diffusion approximations in transient analysis is considered in detail.
