Ripple carry adder circuit. Multiple full adder circuits can be cascaded in parallel to add an N-bit number. For an N- bit parallel adder, there must be N number of full adder circuits. A ripple carry adder is a logic circuit in which the carry-out of each full adder is the carry i...
seventh bit output of the shift register 36 are applied to a voter circuit 48. Thus, the voter circuit 48 determines the binary value of each bit in each group of three equally spaced bits, and produces a binary value representing the majority binary value of those bits. For example, if ...

Thus, we can simplify the logic function of the 1-bit full adder, 4-bit adder, and 4-2 compressor so that we can further reduce the critical path delay and the number of transistors. For example, the truth table of simplified full adder is given in Table 3. Table 3. Truth table of...
