چکیده
A simple relaxation oscillator is designed by directly coupling a RC timing network to a passive S-shaped current-controlled nonlinear resistor and is then modified for chaos. The resulting chaotic oscillator inherits the main features of the relaxation oscillator, which are its low-power consumption and low-voltage operation from single or dual power supplies. These features are attributed to a simple two-bipolartransistor passive nonlinear resistor. PSpice circuit simulations, experimental results and simulations of the derived mathematical models are included. q 2000 Elsevier Science Ltd. All rights reserved.

Time-dependent buckling phenomena of polysilicon micro beams have been demonstrated and reported. These beams are suspended 2 mm above the silicon substrate with dimensions of 100 mm (length) × 2 mm (width) × 2 mm (thickness). When a constant input current is supplied at or above a threshold value, electro-thermally induced buckling occurs. It is observed and recorded that the beams exhibit tim...

This paper presents a real case study on the testing of 8-bit mixed-signal CMOS micro-controller devices by applying the IDDQ testing methodology. The aim of the study is to evaluate the feasibility of using the IDDQ test to enhance the overall fault coverage. Failure analysis operated on the failed sample indicated a good correlation between the fault coverage and the parts that failed the IDD...

This paper extends a study performed by the authors in previous papers dealing with the OBT approach applied to low-pass modulators ‘Microelectron. J. 33/10 (2002) 799’, showing herein the specific features associated to the bandpass case. A practical feedback strategy will be proposed in order to built an effective oscillator, which can be valuable for testing purposes. Critical points of the ...
