چکیده
This paper presents a method to Designing Ripple Carry Adder using CMOS Full-Adders for Energy-Efficient Arithmetic Applications. We present two high-speed and low-power full-adder cells de-signed with an alternative internal logic structure and pass-transistor logic styles that lead to have a reduced powerdelay product (PDP). We carried out a comparison against other full-adders reported as having a low PDP, in terms of speed, power consumption and area. All the full-adders were designed with a 0.18μm CMOS technology, and were tested using a comprehensive test bench that allowed to measure the current taken from the full-adder inputs, besides the current provided from the power-supply. Post-layout simulations show that the proposed full-adders outperform its counterparts exhibiting an average PDP advantage of 80%, with only 40%

Performance analysis of radix-4 adders
We present a radix-4 static CMOS full adder circuit that reduces the propagation delay, PDP, and EDP in carry-based adders compared with using a standard radix-2 full adder solution. The improvements are obtained by employing carry look-ahead technique at the transistor level. Spice simulations using 45 nm CMOS technology parameters with a power supply voltage of 1.1 V indicate that the radix-4...

متن کاملAsynchronous Early Output Dual-Bit Full Adders Based on Homogeneous and Heterogeneous Delay-Insensitive Data Encoding
This paper presents the designs of asynchronous early output dual-bit full adders without and with redundant logic (implicit) corresponding to homogeneous and heterogeneous delay-insensitive data encoding. For homogeneous delay-insensitive data encoding only dual-rail i.e. 1-of-2 code is used, and for heterogeneous delay-insensitive data encoding 1-of-2 and 1-of-4 codes are used. The 4-phase re...
متن کاملEarly Output Hybrid Input Encoded Asynchronous Full Adder and Relative-Timed Ripple Carry Adder
This paper presents a new early output hybrid input encoded asynchronous full adder designed using dual-rail and 1-of-4 delay-insensitive data codes. The proposed full adder when cascaded to form a ripple carry adder (RCA) necessitates the use of a small relative-timing assumption with respect to the internal carries, which is independent of the RCA size. The forward latency of the proposed hyb...
متن کاملA low power carry select adder with reduced area
A carry-select adder can be implemented by using single ripple carry adder and an add-one circuit [1] instead of using dual ripple-carry adders. This paper proposes a new add-one circuit using the first zero finding circuit and multiplexers to reduce the area and power with no speed penalty. For bit length n = 64, this new carry-select adder requires 38 percent fewer transistors than the dual r...
