Abstract
A timing generator reduces operation-dependent power consumption (AC component) and noises generated from a clock distribution circuit itself in distributing a clock, and further reduces a skew attributed to the clock distribution. A clock distribution circuitfor distributing the clock to timing generating sections-to-n has a clock main pathconnected to a main path bufferand a clock return pathconnected to a return path buffer. A load capacity of the main path bufferis equal to that of the return path buffer. Biases of the buffers are the same potential and are generated by a delay locked-loop circuit. A propagation delay time of the clock distribution circuit is controlled so as to be an integral multiple of a clock period.
