  • Current-controlled CMOS ring oscillator circuit
    Patent number: 7321270
    Abstract: A ring oscillator having an odd number of active elements connected in series, where the signal output of one active element is connected to the signal input of the next active element to form a closed ring of active elements. Each active element has a power supply input and a ground connection, a signal input and a signal output, an inverter sub-element having a pair of current mirrors, and a capacitor controlled bias sub-element.
    Type: Grant

  • Integrated circuit including a ring oscillator circuit
    Publication number: 20060232346
    Abstract: An integrated circuit having a signal generator for generating an oscillating signal and a second element utilizing the oscillating signal. The signal generator is a ring oscillator having an odd number of active elements connected in series, where the signal output of one active element is connected to the signal input of the next active element to form a closed ring of active elements. Each active element has a power supply input and a ground connection, a signal input and a signal output, an inverter sub-element having a pair of current mirrors, and a capacitor controlled bias sub-element.
