  • Voltage-controlled oscillator (VCO) with LC circuit and series resistors
    Patent number: 11509266
    Abstract: A system includes a data path and a phase-locked loop (PLL) coupled to the data path. The system also includes a voltage-controlled oscillator (VCO) coupled to the PLL. The VCO includes an LC circuit with first and second differential output terminals. The VCO also includes a first resistor coupled between the first differential output terminal and drain terminals of a first pair of complementary metal-oxide semiconductor (CMOS) transistors. The VCO also includes a second resistor coupled between the second differential output terminal and drain terminals of a second pair of CMOS transistors.
    Type: Grant

  • Frequency synthesizer
    Patent number: 11290118
    Abstract: A frequency synthesizer includes a phase-locked loop (PLL). The PLL includes a first voltage-controlled oscillator (VCO) and a second VCO, each comprising an oscillator, a capacitor bank, and a bias circuit. The capacitor bank is configured to selectably adjust an output frequency of the oscillator. The bias circuit is configured to provide a bias current to the oscillator, and includes a current digital-to-analog converter (IDAC), and an amplifier coupled to the IDAC and configured to drive the oscillator.
