A quadrature voltage-controlled oscillator (QVCO) apparatus including a first VCO, a second VCO, a first energy-storage element, a second energy-storage element, a third energy-storage element and a fourth energy-storage element is provided. The first VCO has a first and a second phase output ends. The second VCO has a third and a fourth phase output ends. A first and a second ends of the first energy-storage element respectively connect to the first and the third phase output ends. A first and a second ends of the second energy-storage element respectively connect to the second and the third phase output ends. A first and a second ends of the third energy-storage element respectively connect to the second and the fourth phase output ends. A first and a second ends of the fourth energy-storage element respectively connect to the first and the fourth phase output ends. |
