  • Time base generator internal voltage-controlled oscillator calibration system and method
    Patent number: 6064947
    Abstract: A successive approximation system and method for calibrating an oscillator in a time base generator application. An oscillator output frequency is compared to a reference frequency. Control logic calibrates an input control current to the oscillator, one bit at a time, through a digital-to-analog converter. The calibrated input control current corrects central frequency errors in the oscillator. Successive approximation continues until all bits are tested.
