Abstract
A method of driving a pixel array includes providing a ramp signal to one or more columns of the pixel array. For each cycle of the ramp signal, the method further includes providing a first row driving signal to at least a first row of the pixel array and a second row driving signal to a second row of the pixel array. A pixel array driver may include a ramp signal generator configured to produce a ramp signal, a first amplifier configured to receive the ramp signal and produce a first amplified ramp signal, and a second amplifier configured to receive the ramp signal and produce a second amplified ramp signal. The first amplified ramp signal may be electrically connected to a first set of pixels of a pixel array, and the second amplified ramp signal may be electrically connected to a second set of pixels of the pixel array.
