The influence of yield model parameters on the probability of defect occurrence

This paper describes the analysis of the influence of yield loss model parameters on the calculation of the probability of arising shorts between conducting paths in IC's. The characterization of the standard cell in AMS 0.8 žm CMOS technology is presented as well as obtained probability results and estimations of yield loss by changing values of model parameters

A 65 nm CMOS Resistorless Current Reference Source with Low Sensitivity to PVT Variations

This paper describes a resistorless current reference source, e.g. for fast communication interfaces. Addition of currents with opposite temperature coefficient (PTC and NTC) and body effect have been used to temperature compensation. Cascode structures have been used to improve the power supply rejection ratio. The reference current source has been designed in a GLOBALFOUNDRIES 65 nm technology. The presented circuit achieves 59 ppm/°C temperature coefficient over range of -40°C to 125°C. Reference current susceptibility to process parameters variation is ± 2.88%. The power supply rejection ratio without any filtering capacitor at 100 Hz and 10 MHz is lower than -142 dB and -131 dB, respectively

A simple tridimensional processing of acceleration measurements for dynamic movements monitoring of sportsmen

Measuring, monitoring and analysis of dynamic movements in sports is becoming more important than ever. Many methods used currently may only be applied in the artificial environment of a laboratory. Other methods require too much processing to be used during a real-time competition. To overcome these difficulties acceleration measurements and a simple method to process them have been proposed. Data processing is based on search and recognition of the characteristic points in the tridimensional representation of acceleration measurements. Three different dynamic movements have been measured: run, jump and punch. The presented results show that the measurements of acceleration and proposed processing may be used to extract movement parameters of a sportsman and monitor the level of his tiredness
