Synchronization of dissipative solitons (DSs) in a system of closed traveling-wave field-effect transistors (TWFETs) is investigated to generate phase-controlled pulse trains. Because of attractive interaction, a DS that rotates along a closed TWFET synchronizes with a DS that rotates along another closed one connected via a resistor, such that both DSs simultaneously pass the connected cell. A pulse train can be generated by outputting part of the DS, whose repetition rate corresponds to the DS rotation frequency. The perturbation theory based on the inverse scattering transform is applied to the model equations to quantify the synchronization behavior of the interacting DSs. Several numerical time-domain calculations are done to show that the synchronization can be utilized to generate a multiphase and low-timing-jitter pulse train.
