Abstract
A ramp driver includes a ramp generator for generating a reference ramp signal, and a ramp delayer for sequentially outputting ramp signals based on the reference ramp signal, and including delay blocks including k output terminals, k being an integer greater than or equal to 2, wherein the delay blocks include k delay circuits sequentially connected to each other, respectively connected to the output terminals, and configured to receive an input ramp signal from a previous one of the delay circuits, receive an input gate clock signal from a previous delay circuit, output an output ramp signal by delaying the input ramp signal, and output an output gate clock signal by inverting the input gate clock signal.
