摘要： A folding circuit and an analog-to-digital converter wherein a response to small signals is improved, a load on a clock signal can be reduced, and the increase of circuit area can be prevented. The circuit includes a reference voltage generating circuit that generates a plurality of differential voltages as reference voltages, and a plurality of amplification circuits that convert differential voltages between the plurality of reference voltages and an analog input voltage to differential currents, and output these differential currents. The output ends of the amplification circuits are alternately connected.
