The purpose of this paper is to present a methodology for the evaluation of the Defect Level in an IC design environment. The methodology is based on the extension of Williams-Brown formula to non equiprobable faults, which are collected from the IC layout, using the information on a typical IC process line defect statistics. The concept of weighted fault(More)
The design of a data acquisition system (DAQ) for a novel Positron Emission Tomography scanner is reported. The PET system, based on long axially oriented scintillation crystals, read out by Hybrid Photon Detectors (HPD), allows 3D parallaxerror free Compton enhanced gamma reconstruction. The DAQ system is composed of several read-out cards, each one(More)
An extension of the well known defect level model by Williams and Brown has been proposed, to account for non-uniform distribution of fault occurrence probabilities. The field experiment reported by Maxwell and Aitken is interpreted in terms alternative (which may also be considered complementary) to those provided by the model by Agrawal, Seth and Agrawal.(More)
In this paper we report the development of a prototype for a new kind of detector intended for scintimammography imaging. Traditional photon counting information is available; moreover digital words representing the amplitude of each event and suitable image elaboration methods significantly enhance detector capabilities. The prototype detector is composed(More)
BIST methods based on the application of a pseudorandom pulse sequence as input stimulus have recently been suggested for testing linear time-invariant (LTI) analog parts [1-3]. In such methods, the input-output cross-correlation function R(t) gives a good estimation of the impulse response of the DUT, h(t), provided the autocorrelation of the pseudorandom(More)
Continuos-Time filters are widely used in signal processing but require a tuning system to align their frequency response. Several tuning techniques have been proposed in the literature, which can be grouped in two basic schemes: master-slave and self-calibrationarrangements. Here we propose a novel tuning approach which can be applied to both tuning(More)
