ABSTRACT:
An arithmetic circuit for addition or subtraction includes a carry or borrow signal control section which includes a transfer gate having N-ch and P-ch transistors for transferring an input carry- or borrow-in as an output carry- or borrow-out. A signal transmission line is coupled to a source line or the earth during a sampling period and precharged during a precharge period, so that both a higher speed transmission of a carry or borrow signal and a reliable carry- or borrow-out signal can be obtained.
