State-space analysis of an IMPATT diode lumped model
David R. Conn, R.H. Mitchell, J.A.C. Stewart · Proceedings of the IEEE · 1970
An accurate small-signal lumped model for the Read-type IMPATT diode is developed which allows formulation using state-space techniques. The analysis also applies to diodes with extended avalanche regions or different geometries, and to large-signal phenomena. The model impedance compares well with the analytic results of Gilden and Hines.
