20090067567 - Fractional frequency divider: A divide-by-N/(N+0.5) frequency divider is disclosed. Two pairs of flip-flops are respectively triggered by an input clock and an inverted input clock, and a frequency-dividing selector is used to select one output of the two pairs of flip-flops as frequency-divided output signal. Two latches are respectively triggered by the input... Agent: Nixon Peabody LLP

20090060118 - Method of operating ripple counter, image sensor having ripple counter, method of operating image sensor, and analog-to-digital converter of image sensor: An example embodiment of an image sensor may include a controller and a plurality of up/down ripple counters. The controller may generate a first control signal and a second control signal. Each of the up/down ripple counters may perform a stop operation or a count operation in response to a...
