Abstract:
A plurality of inductance enhanced interweaved rotary traveling wave oscillators (RTWO) is disclosed. Portions of the transmission line conductors are increased in length and run in parallel. Because the currents in these portions travel in the same direction, the inductance of these inductors is increased. By controlling the length of the transmission line conductors in these areas compared to the lengths where the currents in the oscillators travel in opposite directions, the overall impedance of the oscillators can be increased. Increased impedance leads to lower power and lower phase noise for the oscillators. Additionally, the interweaved oscillators are phase-locked to each other.
