Quaternary Logic Look up Table for Cmos Circuits

Interconnections are increasingly one of the dominant contributors to delay, area and energy consumption in CMOS digital circuits now a days. Multiple Valued Logic (MVL) can decrease the average power required for level transitions and also the number of required interconnections are reduced. So the impact of interconnections on overall energy consumption is reduced. In this paper, a quaternary...

Quaternary Logic Circuits in 2-jum CMOS Technology

Novel quaternary logic circuits, designed in 2-u.m'CMOS technology, are presented. These include threshold detector circuits with an improved output voltage swing and a simple binary-to-quaternary encoder circuit. Based on these, the literal circuits, the quaternary-tobinary decoder, and the quaternary register designs are derived. A novel scheme for improving the power-delay product of pseudo-...

A Novel ±0.5V Ultra High Current Drive and Output Voltage Headroom Current Output Stage with Very High Output Impedance

A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...

Digital CMOS Logic Circuits

1.1. Digital IC Technologies and Logic-Circuit Families The chart in Figure 1 shows the major IC technologies and logic-circuit families that are currently in use. Members of each family are made with the same technology, have a similar circuit structure, and exhibit the same basic features. Each logiccircuit family offers a unique set of advantages and disadvantages. In the conventional style ...
