Large-amplitude voltage edge oscillating in a transmission line with regularly spaced series-connected resonant-tunneling diodes

Abstract

We investigate the increased amplitude of oscillating pulse edge developed in a transmission line periodically loaded with series-connected resonant-tunneling diodes (RTDs). In general, the series-connected RTDs in the middle part of the line can be stabilized in one of the multi-stable states that may disable the proper edge oscillation. We find that it becomes possible to design the line to support such a simple oscillating edge by managing the time required for the state transition of bistable states and the oscillation amplitude increases in proportion to the number of series-connected RTDs through SPICE calculations.
