CIRCUIT FOR TRANSFERRING SIGNAL

摘要

PURPOSE:To excessively reduce wiring delay by permitting a MOS transistor for reducing input capacity to be serial capacity as against the gate capacity of an input MOS transistor when a selecting signal indicates nonselection. CONSTITUTION:The P-type MOS transistor MP1 and the two N-type MOS transistors MN1 and MN2 are connected in serial and a common clock line 100 is connected with the gate electrode of the transistor MN1. A block selection line SBi is connected with the gate electrode of the transistor MP1 and the transistor MN2 and a block output line Oi is connected with a connecting point between the drain electrodes of the transistor MP1 and the transistor MN1. The transistor MN2 constitutes serial capacity as against capacity between a gate and channel in the transistor MN1 as the input MOS transistor so as to reduce input capacity at the time of nonselection.
