Tunable distributed oscillator with flexible electrical length

A distributed oscillator, comprising:

• a transmission-line segment having a first end, a second end, and a middle portion between the first end and the second end;
• a first oscillator coupled with the first end;
• a second oscillator coupled with the second end;
• a first inductive matching circuit coupled between the first oscillator and the middle portion;
• and
• a second inductive matching circuit coupled between the second oscillator and the middle portion.

A communication device, comprising:

• a first component;
• a second component;
• and
• a distributed oscillator comprising a plurality of units,
• wherein the plurality of units includes:
• a first unit proximate to the first component, and
• a second unit proximate to the second component and coupled in series with the first unit, and wherein each of the first unit and the second unit includes:
• a transmission line having a first end, a second end, and a portion between the first end and the second end,
• a first oscillator coupled with the first end,
• a second oscillator coupled with the second end,
• a first circuit comprising one or more first inductors and coupled between the first oscillator and the portion, and
• a second circuit comprising one or more second inductors and coupled between the second oscillator and the portion.
