We describe a system for generating accurate tests for bridge faults (with or without feedback) in CMOS ICs. We present the Test Guarantee Theorem, which allows for accurate test generation for feedback bridge faults via topological analysis of the feedbackin uenced region of the faulted circuit (without the need for any post-test veri cation or explicit examination of inversion parity). We des...

In the modern opto-electronic transceiver designs, the high-speed frontend circuits of the optical receivers are considerably focused on the circuit designs. Many different topologies have been published since the optical fiber was applied for transmitting high data rate signal. In the optical transceivers, the transimpedance amplifier (TIA) plays a critical role in converting the input current...

Class D amplifiers (amps) are conventionally designed as feedforward circuits primarily due to the difficulty of feeding back the digital pulse width modulated output. We analytically investigate the design of Class D amps with feedback and propose a feedback circuit design. We show that the performance of current-art low-power (mWs) low-voltage (1.11.4V) Class D amps embodying our feedback des...

Bifurcations leading to complex dynamical behaviour of non-linear systems are often encountered when the characteristics of feedback circuits in the system are varied. In systems with many unknown or varying parameters, it is an interesting, but difficult problem to find parameter values for which specific bifurcations occur. In this paper, we develop a loop breaking approach to evaluate the in...

We demonstrate the control of chaos in a nonlinear circuit constructed from readily available electronic components. Control is achieved using recursive proportional feedback, which is applicable to chaotic dynamics in highly dissipative systems and can be implemented using experimental data in the absence of model equations. The application of recursive proportional feedback to a simple electr...

A circuit which simulates the electrical conduction characteristics of the neuron has been modified by the addition of a feedback loop to simulate the electrical properties of some of the "specialized" tissues of the mammalian heart. It is suggested that there is similar electrical feedback in the muscle cells which is responsible for their electrical properties, and possible relationships betw...

The thalamus and neocortex are intimately interconnected via a reciprocal arrangement of feedforward and feedback projections. In this issue of Neuron, Crandall et al. (2015) provide key insight into the functional dynamics of feedback projections and reveal the cellular and circuit mechanisms that underlie a rate-dependent switch in the net influence, suppression versus excitation, that cortex...

My thesis aimed to elucidate general organizing principles underlying the modulation of neural circuits. These circuits are flexible constructs that, when modulated, can occupy many distinct states and produce different output patterns. Distinct circuit states can also produce the same output pattern in some cases. However, understanding the mechanisms and consequences of this latter phenomenon...

− This paper presents a new output feedback technique for synchronizing chaotic circuits. In particular, it is shown that synchronization can be systematically achieved via a scalar signal for a large class of chaotic systems. The approach is successfully applied to the recently proposed Chua’s circuit with x|x| nonlinearity. Key-words: – Chaotic circuits, Synchronization, Feedback techniques, ...

This paper deals with a feedback control strategy for chaos suppression. The proposed strategy is an input–output control scheme which comprises an uncertainty estimator and an asymptotic linearizing feedback. The developed control scheme allows chaos suppression in spite of modeling errors and parametric variations.
