摘要:
A voltage-controlled oscillator (VCO) module including a first VCO unit, a second VCO unit, and a matching circuit is provided. The first VCO unit includes a first terminal and a second terminal and generates a first oscillator signal. The second VCO unit is coupled to the first VCO unit and generates a second oscillator signal. The matching circuit is coupled between the first VCO unit and second VCO unit. The matching circuit includes a plurality of inductor modules respectively coupled between the first terminal of the first VCO unit and the second VCO unit, between the first terminal and the second terminal of the first VCO unit, and between the second terminal of the first VCO unit and the second VCO unit. Furthermore, a method for generating oscillator signals is also provided.
