In order to produce a self-sustaining oscillation, there necessarily must be feedback from the output to the input, sufcient gain to overcome losses in the feedback path, and a resonator. There are number of ways to classify oscillator circuits, one of those being the distinction between one-port and two-port oscillators. The one-port oscillator has a load and resonator with a negative resistance at the same port, while the two-port oscillator is loaded in some way at the two ports. In either case there must be a feedback path, although, in the case of the one-port, this path might be internal to the device itself.
