Abstract

PURPOSE:To obtain a sequential comparing circuit which is capable of setting the power consumption to a current value of a C-MOS level as a whole, by combining in order an exclusive OR circuit having a specific configuration, and an exclusive NOR circuit. CONSTITUTION:An exclusive OR circuit A to which 2 transistors Trc1 and Trc2 have been added, and an exclusive NOR circuit B to which 2 transistors Trc3 and Trc4 have been added are placed alternately. The exclusive OR circit A is a complementary circuit and the power consumption is a current value of a C- MOS level. When Vp of both data Xn+1 and Yn+1 is grounded, a node Np becomes Vp. Accordingly, when the Trc1 is at on state, that is to say, an output Cn of a coincidence detecting circuit of data Xn, Yn is in a ground level, Cn+1 becomes a Vp level. In the event of dissidence of the data Xn+1, Yn+1, a coincidence signal becomes a ground level irespective of Cn. The power consumption of the exclusive NOR circuit also becomes a C-MOS level in the same way.
