Analogue IC Design: the Current Mode Approach

IEEE transactions on very large scale integration (VLSI) systems

In this paper, a hybrid 1-bit full adder design employing both complementary metal–oxide–semiconductor (CMOS) logic and transmission gate logic is reported. The design was first implemented for 1 bit and then extended for 32 bit also. The circuit was implemented using Cadence Virtuoso tools in 180-and 90-nm technology. Performance parameters such as power, delay, and layout area were compared with the existing designs such as complementary pass-transistor logic, transmission gate adder, transmission function adder, hybrid pass-logic with static CMOS output drive full adder, and so on. For 1.8-V supply at 180-nm technology, the average power consumption (4.1563 $\mu $ W) was found to be extremely low with moderately low delay (224 ps) resulting from the deliberate incorporation of very weak CMOS inverters coupled with strong transmission gates. Corresponding values of the same were 1.17664 $\mu $ W and 91.3 ps at 90-nm technology operating at 1.2-V supply voltage. The design was further extended for implementing 32-bit full adder also, and was found to be working efficiently with only 5.578-ns (2.45-ns) delay and 112.79- $\mu $ W (53.36- $\mu $ W) power at 180-nm (90-nm) technology for 1.8-V (1.2-V) supply voltage. In comparison with the existing full adder designs, the present implementation was found to offer significant improvement in terms of power and speed.

Performance Analysis of a Low-Power High-Speed Hybrid 1-bit Full Adder Circuit

This paper presents a comparative study of high-speed and low-voltage full adder circuits. Our approach is based on hybrid design full adder circuits combined in a single unit. A high performance adder cell using an XOR-XNOR (3T) design style is discussed. This paper also discusses a high-speed conventional full adder design combined with MOSCAP Majority function circuit in one unit to implement a hybrid full adder circuit. Moreover, it presents low-power Majority-function-based 1-bit full addersthat use MOS capacitors (MOSCAP) in its structure. This technique helps in reducing power consumption, propagation delay, and area of digital circuits while maintaining low complexity of logic design. Simulation results illustrate the superiority of the designed adder circuits over the conventional CMOS, TG, and hybrid adder circuits in terms of power, delay, power delay product (PDP), and energy delay product (EDP). Postlayout simulation results illustrate the superiority of the newly designed majority adder circuits against the reported conventional adder circuits. The design is implemented on UMC0.18 µm process models in Cadence Virtuoso Schematic Composer at 1.8 V single-ended supply voltage, and simulations are carried out on Spectre S.

Performance analysis of high speed hybrid CMOS full adder circuits for low voltage VLSI design

This paper presents comparative study of high-speed, low-power and low voltage full adder circuits. Our approach is based on XOR-XNOR design full adder circuits in a single unit. A low power and high performance 9T full adder cell using a design style called “XOR (3T)” is discussed. The designed circuit commands a high degree of regularity and symmetric higher density than the conventional CMOS design style as well as it lowers power consumption by using XOR (3T) logic circuits. Gate Diffusion Input (GDI) technique of low-power digital combinatorial circuit design is also described. This technique helps in reducing the power consumption and the area of digital circuits while maintaining low complexity of logic design. This paper analyses, evaluates and compares the performance of various adder circuits. Several simulations conducted using different voltage supplies, load capacitors and temperature variation demonstrate the superiority of the XOR (3T) based full adder designs in term of delay, power and power delay product (PDP) compared to the other full adder circuits. Simulation results illustrate the superiority of the designed adder circuits against the conventional CMOS, TG and Hybrid full adder circuits in terms of power, delay and power delay product (PDP).

Comparative Performance Analysis of XOR- XNOR Function Based High-Speed CMOS Full Adder Circuits For Low Voltage VLSI Design

This paper presents a comparative study of highspeed, low-power and low voltage full adder circuits. Our approach is based on XOR-XNOR (4T) design full adder circuits combined in a single unit. This technique helps in reducing the power consumption and the propagation delay while maintaining low complexity of logic design. Simulation results illustrate the superiority of the designed adder circuits against the conventional CMOS, TG and Hybrid adder circuits in terms of power, delay and power delay product (PDP) at low voltage. Noise analysis shows designed full adder circuit's work at high frequency and high temperature satisfactorily. Simulation results reveal that the designed circuits exhibit lower PDP, more power efficiency and faster when compared to the available full adder circuits at low voltage. The design is implemented on UMC 0.18µm process models in Cadence Virtuoso Schematic Composer at 1.8 V single ended supply voltage and simulations are carried out on Spectre S.

Design analysis of XOR (4T) based low voltage CMOS full adder circuit

In a very fast growth of very large scale integration (VLSI) technology, it is the demand and necessity of time to achieve a reliable design with low power consumption. The quantum dot cellular automata (QCA), due to its small size, very high switching speed and ultra-low power consumption, can be an alternative for CMOS VLSI technology at nano-scale level. A novel 5-input majority gate for QCA is proposed in this paper which is suitable for designing QCA circuits in a simple and symmetric manner. Based on it, we have designed a full adder with some physical proofs provided for the functions of Boolean techniques to verify the functionality of the proposed devices properly. For computer simulations analysis, functionality of full adder has been checked using the QCADesigner tool. Both simulation results and physical proofs confirm the usefulness of our proposed gate design for designing any digital circuit.
