  • Low-power and low-noise comparator having inverter with decreased peak current
    Publication number: 20040257128
    Abstract: Low-power and low-noise CDS (correlated double sampling) comparators for use with a CIS (CMOS image sensor) device are provided. A CDS comparator is constructed using one of various low-power inverters that provide decreased instantaneous transition currents at a logic threshold voltage. The use of such low-power inverters in CDS comparators enables a significant reduction in power consumption and noise in the CIS device, or other devices that implement such CDS comparators and/or inverters.
