  • Ramp generator for image sensor ADC
    Patent number: 6956413
    Abstract: A ramp generator includes a resistance ladder supplied with a constant current. Switches are closed in sequence by a shift register to provide a stepped ramp output. The constant current is controlled by referencing an on-chip bandgap voltage that is used as an input to a feedback circuit controlling current through a reference resistor ladder.
    Type: Grant
