Abstract
The present invention proposes a multiple-push oscillator for providing a high-frequency signal. The multiple-push oscillator combines N (at least 3) fundamental oscillators. Through the design of circuit connection, the N fundamental oscillators will operate at odd modes with phase differences of 360/N degrees between their output currents to obtain an output signal of frequency at least three times as large as that of the fundamentals. Therefore, a high-frequency signal source can be more easily designed by the present invention. Moreover, the present invention has the characteristics of high transistor gain and high resonator Q factor.
