摘要
A voltage-controlled oscillator (VCO) having a bandpass filter includes an oscillation circuit and a bandpass filter. The oscillation circuit outputs a first oscillation frequency with a harmonic distortion according to a tuning voltage. The first oscillation frequency is then input to the bandpass filter and the harmonic distortion of the first oscillation frequency is filtered. Therefore, a second oscillation frequency without the harmonic distortion is output from the bandpass filter. The invention is characterized by that the bandpass filter that removes the harmonic distortion from the VCO.
