Abstract
A voltage controlled oscillator is provided. The voltage controlled oscillator includes a differential transmission line and another transmission line, which can include a second differential transmission line or other suitable transmission lines. An active device connected to the differential transmission line and the other transmission line controls the current flow between the two transmission lines. A tuning circuit connected to the active device, such as a bias voltage, controls an oscillation frequency of a signal on the differential transmission line and the other transmission line, such as by controlling the level of current flow.
