A new full-adder circuit for pipeline architecture is proposed. Compared with other full-adder circuits, it has high operational speed smallest transistor number and the lowest power/speed ratio. This new full-adder cell is then used to design a pipelined 8×8-b multiplier-accumulator (MAC). In the MAC, a special pipelined structure is designed to reduce the latency. The whole chip is fabricated in a 0.8 μm Single-Poly-Double-Metal CMOS process and the post-layout simulation of the pipelined 1-bit full adder can work up to 350 MHz. The whole chip which contains 4200 transistor are measured to operate at 125 MHz using 3.3 V power supply.
