  • Stepped ramp signal generator and image sensor using the same
    Patent number: 9036041
    Abstract: A stepped ramp signal generator includes a ramp signal generation unit configured to provide final values of previous stepped ramp signals as initial values of the next stepped ramp signals. The ramp signal generation unit includes a plurality of matching resistors, and a plurality of holders installed between the matching resistors, each holder storing a final value across a previous matching resistor and providing the final value to a next matching resistor.
    Type: Grant
