  • Voltage-controlled oscillator and PLL circuit in which same is used
    Patent number: 11206028
    Abstract: A voltage-controlled oscillator includes: a first transistor with its gate connected to an input terminal, its source connected to a first power supply, and its drain connected to a first node; a second transistor with its gate connected to a first bias voltage, its source connected to a second power supply, and its drain connected to the first node; and an inverter ring connected between the first node and the first power supply. The inverter ring is constituted by a plurality of stages of inverters connected in series, and an output of a final-stage inverter is connected to an output terminal and an input of an initial-stage inverter.
    Type: Grant
