In one embodiment, a method includes generating, by a LCVCO, a first signal having a first phase based on a resonant frequency of a first LC tank; generating, by a second LCVCO, a second periodic signal having a second phase based on a resonant frequency of a second LC tank; determining a phase offset between the first LC tank and the second LC tank based on the first and second signals; generating a first output signal and a second output signal based on the determined phase offset; and adjusting the phase offset such that the phase offset is substantially equal to a predetermined phase offset. In one embodiment, the adjusting comprises modulating a first impedance of the first LC tank based on the first output signal, and/or modulating a second impedance of the second LC tank based on the second output signal. |
