Abstract
A standing wave oscillator is described. The standing wave oscillator includes a transmission line, and an even number of gain stages. Each gain stage is connected to the transmission line, and each gain stage is located at a respective location along a length of the transmission line. The gain stages are configured to generate a standing wave oscillator signal along the length of the transmission line, when a supply voltage is applied to at least one end of the transmission line. The location of each gain stage is non-coincidental with an expected location of maximum amplitude of the standing wave oscillator signal.
