This paper considers the stabilization of switching nonlinear models by switching between the subsystems. We assume that arbitrary switching between two subsystems is possible once a subsystem has been active for a predefined number of samples. We use a Takagi-Sugeno representation of the models and a switching Lyapunov function is employed to develop sufficient stability conditions. If the con...
This paper presents significant improvements in the generation of analog signals for on-chip analog circuit testing. In particular, the novel oscillators proposed here can achieve signal-to-noise ratios far greater than previous designs, while remaining area-efficient. One particular example illustrates a 30 dB improvement in the SNR. Alternatively, signals can be generated with the same SNR as...
High-frequency switching of power transistors in electronic systems can cause electromagnetic emissions. Simple approaches for reducing high-frequency disturbances, such as inserting an additional gate resistor, lead to increased losses. This makes achieving both compatibility and efficiency difficult. Active drivers help find a trade-off between these two. Typically, only narrow-band disturban...
The growing demand for bandwidth and energy efficiency requires new solutions signal detection processing. We demonstrate a concept high-bandwidth with low-speed photodetectors electronics. method is based on the parallel optical sampling of sinc-pulse sequences provided by Mach-Zehnder modulator. For electronic processing this enables to divide <inline-formula xmlns:mml="http://www.w3.org/1998...
We study computational questions related with the stability of discrete-time linear switching systems with switching sequences constrained by an automaton. We first present a decidable sufficient condition for their boundedness when the maximal exponential growth rate equals one. The condition generalizes the notion of the irreducibility of a matrix set, which is a well known sufficient conditi...
The speech-to-noise ratio (SNR) in an environment plays a vital role in speech communication for both normal-hearing (NH) and hearing-impaired (HI) listeners. While hearing-assistance devices attempt to deliver as favorable an SNR as possible, there may be discrepancies between noticeable and meaningful improvements in SNR. Furthermore, it is not clear how much of an SNR improvement is necessar...
Trigonometric functions are among the most useful functions in the digital signal processing applications. The design introduced in this paper computes the trigonometric functions by means of the systolic arrays. The method for computing these functions for an arbitrary angle, , is the CORDIC algorithm. A simple standard cell is used for the systolic array. Due to the fixed inputs, in some...
An analytical model for two-pass optical amplifier with arbitrary beams overlap has been developed which generalized the classical theory of Frantz-Nodvik for single pass amplifier. The effect of counterpropagating beams on gain and output energy fluence included in the model. Moreover, the appropriate limiting relations for two special cases of weak input signal and saturation state of the amp...
