Numerous efforts have made to balance the tradeoff between power consumption, area and speed of a design. While studying the design at the two extreme ends of the design spectrum, namely the ultra-low power with acceptable performance at one end and high performance with power within limit at the other has not made. One solution to achieve the ultra-low power consumption is to operate the desig...

Variable-threshold threshold elements (V-T threshold elements) are threshold elements in which the weights are fixed while the threshold may be varied. When the threshold is varied, a set of functions is generated. A concept termed complete uniformity, analogous to complete monotonicity, is shown to be a necessary condition for a set of functions to be realizable by a single V-T threshold eleme...

In recent years, there has been renewed interest in Threshold Logic (TL), mainly as a result of the development of a number of successful implementations of TL gates in silicon, with improved performance and power dissipation compared to conventional logic. In this work, the problem of estimating the delay of circuits based on the Charge Recycling Threshold Logic (CRTL) gate implementation is a...

We propose dynamic resistive threshold-logic (DRTL) design based on non-volatile resistive memory. A threshold logic gate (TLG) performs summation of multiple inputs multiplied by a fixed set of weights and compares the sum with a threshold. DRTL employs resistive memory elements to implement the weights and the thresholds, while a compact dynamic CMOS latch is used for the comparison operation...

Threshold gates consisting of resonant tunneling diodes (RTDs) in conjunction with HBTs or CHFETs or MOSFETs can form extremely compact, ultrafast, digital logic alternatives, and may be used for digital signal processing applications in the near future. The resonant tunneling phenomenon causes these circuits to exhibit super-high-speed switching capabilities. Additionally, by virtue of being t...

Magnetoelectronic devices, which combine ferromagnetic materials with conventional silicon structures, o er the potential to add non-volatile storage to electronic systems, eliminating their vulnerability to data loss due to power supply interruptions. We present a set of circuits, based on the Hybrid Hall E ect device, that combine logic with non-volatile storage. These circuits can be con gur...

A variable threshold voltage keeper circuit technique is proposed for simultaneous power reduction and speed enhancement of domino logic circuits. The threshold voltage of a keeper transistor is dynamically modified during circuit operation to reduce contention current without sacrificing noise immunity. The variable threshold voltage keeper circuit technique enhances circuit evaluation speed b...

Originating from work in operations research the cutting plane refutation system CP is an extension of resolution, where unsatisfiable propositional logic formulas in conjunctive normal form are recognized by showing the non-existence of boolean solutions to associated families of linear inequalities. Polynomial size CP proofs are given for the undirected s-t connectivity principle. The subsyst...
