  • RC oscillator with additional inverter in series with capacitor
    Patent number: 9300247
    Abstract: In an electronic device, an RC oscillator generally includes a resistor, a capacitor and at least one inverter. The resistor and capacitor generate a time-varying voltage. The time-varying voltage is provided to the at least one inverter to cause a clock signal to propagate therethrough. The clock signal propagates with a time delay that is at least partially dependent on a supply voltage. The supply voltage is adjusted to maintain the time delay at almost a constant value.
    Type: Grant
    Filed: May 6, 2013
    Date of Patent: March 29, 2016
    Assignee: TEXAS INSTRUMENTS INCORPORATED
    Inventors: Per Torstein Roine, Danielle L Griffith, Ryan A Smith
