This paper makes a critical investigation of six programmable delay-producing elements used in present day technology. In signal processing applications, these circuits are capable of incorporating a fixed duration of delay, while keeping the signal integrity intact as well. This comparative study among the six delay-producing elements aids the design engineers in selecting an appropriate delay generating...
Various electronic circuits require a trigger pulse to initiate their operations. Circuits capable of producing very precise duration pulses can be utilized to trigger such circuits. Different designs of trigger pulse generator (TPG) circuit realized by employing optimal delay element (DE) and an XOR logic gate have been reviewed in this work. Profound study of programmable and non-programmable DEs...
Demand for low power circuits is increasing and an easy way to meet low power requirement is to scale down the supply voltage. When the power supply is less than the threshold voltage of the transistors, the circuit is said to be operating in the subthreshold region. This work presents a novel 9T subthreshold SRAM cell. Some important features of the proposed design are employment of single-ended...
This paper proposes a compact, low power high frequency trigger pulse generator circuit. Delay-introducing circuit that can incorporate a certain amount of delay during signal processing while maintaining the signal integrity is utilized in the proposed design. This paper evaluates performance of various delay-introducing circuits in terms of different design matrices. Further, this paper exploits...
Technology scaling driven by the benefit of integration density, high-speed of operation and low-power dissipation, has overcome many barriers over the last four decades. Currently, it is facing even more hurdles, which are more critical than earlier. One of them is variability. Variability is becoming a metric of equal importance as power, delay, and area. This work attempts to perform power and...
Multivalued Logic has attracted substantial interest of digital designers due to its potential of enhancing data content per unit area. This paper extensively analyses transient characteristics of CNFET-based ternary inverter and compares the variability of its different design metrics with those of CNFET-based binary inverter and shows that the variability of parameters of ternary inverter are much...
This paper presents a study of MTJ-based logic circuit in terms of propagation delay, power dissipation, and power-delay product.
