Abstract:
1. A method comprising: generating, by a first inductor-capacitor based voltage-controlled oscillator (LCVCO) that includes a first LC tank, a first periodic signal having a frequency and a first phase based on a resonant frequency of the first LC tank; generating, by a second LCVCO that includes a second LC tank, a second periodic signal having the frequency and a second phase based on a resonant frequency of the second LC tank; determining, by a phase detector, a phase offset between the first LC tank and the second LC tank based on the first and second periodic signals; generating, by the phase detector, a first output signal and a second output signal based on the determined phase offset; adjusting the phase offset such that the phase offset is substantially equal to a predetermined phase offset, the adjusting comprising: summing the first output signal with a first adjustment signal to generate a first adjusted signal and summing the second output signal with a second adjustment signal to generate a second adjusted signal; wherein:
