Title:
RAMP MODULATION ANALOG-TO-DIGITAL CONVERTER FOR IMAGER
Document Type and Number:
Japanese Patent JP2006050231
Kind Code:
A
Abstract:
To provide an analog-to-digital converter that substantially decreases the analog-to-digital conversion time in an imager.
The analog-to-digital converter is configured to include: a ramp generator; a control circuit connected to the ramp generator, the control circuit controls the ramp generator so as to generate a ramp-modulated analog ramp output and a digital code corresponding to each analog ramp output; and a comparator for comparing an analog input signal with the analog ramp output and generating a signal when both of them are equal to each other.
