Patent ID: 8390388

Claim:
An oscillator, comprising: a first amplifier, the first amplifier being configured for outputting a first amplifier output signal and a second amplifier output signal; a routing device, the routing device being connected to the first amplifier and being configured for receiving the first and second amplifier output signals, the routing device configured for splitting the first amplifier output signal to provide a first routing device output signal and a second routing device output signal, the routing device further configured for splitting the second amplifier output signal to provide a third routing device output signal and a fourth routing device output signal; a first resonator, the first resonator being connected to the routing device via a first set of transmission lines, the first resonator being configured for receiving the first and second routing device output signals, the first and second routing device output signals causing the first resonator to oscillate and to generate a first resonator output signal; and a second resonator, the second resonator being connected to the routing device via a second set of transmission lines, the second resonator being configured for receiving the third and fourth routing device output signals, the third and fourth routing device output signals causing the second resonator to oscillate and to generate a second resonator output signal, wherein the oscillator is a differential oscillator and implements switching of the first set of transmission lines for providing inversion, the first resonator and the second resonator being driven at a same frequency and one hundred-eighty degrees out-of-phase with respect to each other.
