TL;DR: The equivalence of the nonlinear optimal cycle time calculation problem to an associated and simpler linear programming (LP) problem is proved and a LP-based algorithm which is guaranteed to obtain the optimal cycleTime for arbitrary circuits controlled by a general class of multiphase overlapped clocks is presented.
Abstract: The authors present a succinct formulation of the timing constraints for latch-controlled synchronous digital circuits. It is shown that the constraints are mildly nonlinear. The equivalence of the nonlinear optimal cycle time calculation problem to an associated and simpler linear programming (LP) problem is proved. A LP-based algorithm which is guaranteed to obtain the optimal cycle time for arbitrary circuits controlled by a general class of multiphase overlapped clocks is presented. The formulation and an initial implementation of the algorithm on some example circuits are illustrated. >

TL;DR: In this article, a logic gate implementation using a linear resistor, a linear capacitor and four CMOS-transistors with a battery is presented, which produces cubic-like nonlinearity.
Abstract: It was shown recently [Murali et al., Phys. Rev. Lett. 102, 104101 (2009)] that when one presents two square waves as input to a two-state system, the response of the system can produce a logical output (NOR/OR) with a probability controlled by the interplay between the system noise and the nonlinearity (that characterizes the bistable dynamics). One can switch or “morph” the output into another logic operation (NAND/AND) whose probability displays analogous behavior; the switching is accomplished via a controlled symmetry-breaking dc input. Thus, the interplay of nonlinearity and noise yields flexible and reliable logic behavior, and the natural outcome is, effectively, a logic gate. This “logical stochastic resonance” is demonstrated here via a circuit implementation using a linear resistor, a linear capacitor and four CMOS-transistors with a battery to produce a cubiclike nonlinearity. This circuit is simple, robust, and capable of operating in very high frequency regimes; further, its ease of implementation with integrated circuits and nanoelectronic devices should prove very useful in the context of reliable logic gate implementation in the presence of circuit noise.

TL;DR: The program TRANALYZE generates a gate-level representation of an MOS transistor circuit that has the same generality and accuracy as switch-level simulation, generating models for a wide range of technologies and design styles, while expressing the detailed effects of bidirectional transistors, stored charge, and multiple signal strengths.
Abstract: The program TRANALYZE generates a gate-level representation of an MOS transistor circuit. The results model contains only four-valued unit and zero delay logic primitives, suitable for evaluation by conventional gate-level simulators and hardware simulation accelerators. TRANALYZE has the same generality and accuracy as switch-level simulation, generating models for a wide range of technologies and design styles, while expressing the detailed effects of bidirectional transistors, stored charge, and multiple signal strengths. It produces models with size comparable to ones generated by hand. >

TL;DR: The paper includes a performance comparison analysis of Si and GaAs FET's and switching circuits which indicates that, for equivalent speed-power product operation, GaAs IC's should be about six times faster than Si IC's.
Abstract: Recent advances of GaAs integrated circuit fabrication technology have made possible the demonstration of ultrahigh performance GaAs digital ICs with up to 64 gate MSI circuit complexities and with gate areas and power dissipations sufficiently low to make VLSI circuits achievable. The authors evaluate, based on the current state of GaAs IC technology and the fundamental device physics involved, the prospects of achieving an ultrahigh-speed VLSI GaAs IC technology. GaAs IC fabrication and logic circuit approaches is reviewed. The experimental performance results are compared for the leading GaAs logic circuit approaches, both for simple ring oscillators and for more complex sequential logic circuits.

TL;DR: In this paper, a plurality of flip-flops are used to form a feedback shift register, which is coupled to the AND logic array outputs of a combinational circuit which also includes and OR logic array.
Abstract: An easily testable integrated logic circuit utilizes a plurality of flip-flops to form a feedback shift register. In some embodiments, means are provided for selectively forming the flip-flops into a feedback shift register and for selectively supplying either the flip-flop contents or a random signal as partial inputs to the combinational logic circuit. In other embodiments, the feedback shift register is coupled to the AND logic array outputs of a combinational circuit which also includes and OR logic array.
