On condition of dichotomy, it is pointed out that in Lorenz and a kind of Rössler-like system chaotic attractors or limit cycles will disappear if nonlinearity of the product of two variables is replaced by some single variable nonlinearity, for example, nonlinearity of Chua’s circuit. Furthermore, an extended Chua’s circuit with two nonlinear functions is presented. By computer simulation it i...

Using computer-aided circuit simulation, the speed of RTD-based bistable circuits has been evaluated in terms of device parameters, such as the transistor’s fT and fmax, and circuit parameters, such as sizing. Two topologies studied in this work are: 1) monostable-to-bistable transition logic element (MOBILE), and 2) quantum bistable logic circuit (QBL). The transistors studied in this paper ar...

All practical digital circuits are usually a mixture of combinational and sequential logic. Flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. The concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...

We discuss a quantum non-demolition measurement (QNDM) protocol to estimate the derivatives of cost function with computer. The function, which is supposed be classically hard evaluate, associated average value operator. Then computer used efficiently extract information about and its derivative by evolving system so-called variational circuit. To this aim, we propose use detector that allows u...

6 LLE Review, Volume 73 A streak camera is an electro-optic instrument capable of resolving high-speed, low-repetition-rate, pulsed laser phenomena. The basis of the instrument is a streak tube. The image of the light to be analyzed is focused onto a photocathode at the input end of the streak tube. The photocathode emits electrons in response to the intensity of the light. The electrons, focus...

Today's intermediate-scale quantum computers, although imperfect, already perform computational tasks that are manifestly beyond the capabilities of modern classical supercomputers. However, so far, quantum-enabled large-scale solutions have been realized only for limited set problems. Here a hybrid algorithm based on phase estimation and optimization circuit width depth is employed solving spe...

A time-domain, non-Monte Carlo method for computer simulation of electn'cal noise in nonlinear dynamic circuits with arbitrary excitations and arbitrary large-signal waveforms is presented. This time-domain noise simulation method is based on results from the theory of stochastic differential equations. The noise simulation method is general in the following sense. Any nonlinear dynamic circuit...

Jointly sponsored by ACM and IEEE, the International Conference on Computer-Aided Design (ICCAD) is a premier forum to explore new challenges, present leading-edge innovative solutions, identify emerging technologies in electronic design automation (EDA) research areas. ICCAD covers full range of computer-aided (CAD) topics—from device circuit levels up through system level, as well post-CMOS d...

The Cardinality Constrained Circuit Problem (CCCP) is the problem of finding a minimum cost circuit in a graph where the circuit is constrained to have at most k edges. The CCCP is NP-Hard. We present classes of facet-inducing inequalities for the convex hull of feasible circuits, and a branch-and-cut solution approach using these inequalities. †Current Address: Argonne National Lab, Math and C...
