摘要：
A quadrature voltage controlled oscillator includes oscillation circuits for generating in-phase and quadrature-phase oscillation signals that are used to generate in-phase and quadrature-phase output signals. A compensation circuit adjusts biasing in the oscillation circuits depending on a phase relationship between the in-phase and quadrature-phase output signals to automatically control the phase relationship between the oscillation signals.
