Selective exposure to visible light is used to permanently trim the resonant wavelengths of coupled ring-resonator filters and delay-lines realized on a chalcogenide As2S3 platform. Post-fabrication manipulation of the circuit parameters has proved an effective tool to compensate for technological tolerances, targeting demanding specifications in photonic integrated circuits with no need for al...

We investigate the movement of small amplitude parts in a coupled chaotic system. The system consists of chaotic circuits using CMOS ring oscillators and capacitors as coupling elements. In the case of coupling 25 chaotic circuits, irregular movements of small amplitude parts are observed for the same parameter and different initial values. This is a kind of spatio-temporal phenomena. We focus ...

It is shown that, through an extension of the describing function technique and of Loeb's stability criterion, the number and the characteristics of the periodic attractors occurring in one-dimensional arrays of coupled Chua's circuits can be accurately predicted. The technique can also be applied to the investigation of chaotic attractors, by de ning a suitable distortion index and to the stud...

One-dimensional arrays of nonlinear electronic circuits are shown to support propagation of pulses when operating in a locally bistable regime, provided the circuits are under the influence of a global noise. These external random fluctuations are applied to the parameter that controls the transition between bistable and monostable dynamics in the individual circuits. As a result, propagating f...

The transconductance characteristics of MOS transistors realized in 0.18 p n CMOS technology have B zerotemperature coefticient (ZTC) bias point. The presence of this point influences performance of both analog and digital circuits. The offset voltage drift in a saurce-coupled differential pair strongly increases, if the transistor drain currents are equal to the bias currents of ZTC point. It ...

The self-assembly of molecularly precise nanostructures is widely expected to form the basis of future high-speed integrated circuits, but the technologies suitable for such circuits are not well understood. In this work, DNA self-assembly is used to create molecular logic circuits that can selectively identify specific biomolecules in solution by encoding the optical response of near-field cou...

We present the concept of circuit nanoelements in the optical domain using plasmonic and nonplasmonic nanoparticles. Three basic circuit elements, i.e., nanoinductors, nanocapacitors, and nanoresistors, are discussed in terms of small nanostructures with different material properties. Coupled nanoscale circuits and parallel and series combinations are also envisioned, which may provide road map...

Detection of secreted signaling molecules by cognate cell surface receptors is a major intercellular communication pathway in cellular circuits that control biological processes. Understanding the biological significance of these connections would allow us to understand how cellular circuits operate as a whole. Membrane-tethered ligands are recombinant transgenes with structural modules that al...

Among three chip-level electrostatic discharge (ESD) test standards, which were human-body model (HBM), machine model (MM), and charged-device model (CDM), the CDM ESD events became critical due to the larger and faster discharging currents. Besides input/output (I/O) circuits which were connected to I/O pads, core circuits also suffered from CDM ESD events caused by coupled currents between I/...
