ABSTRACT: Owing to the ever-increasing clock frequency in digital circuits and systems, simultaneous switching noise (SSN), caused by fast rise/fall pulse edges in combination with parasitic inductance in the power supply distribution network, is becoming a severe problem in many high-speed digital system designs. It is quantitatively shown that the influence of SSN, which is negligible when the rise/fall time is long (>5 ns), becomes a critical factor, limiting system performance in the subnanosecond rise time region. Based on theoretical analyses and computational simulations in respect to various packaging techniques, technical solutions and design guidelines for reducing SSN are summarised.

ABSTRACT: Simultaneous switching noise (SSN) caused by parasitic inductance
in the power supply distribution network is a severe problem in high
speed digital circuits and systems. The influence of SSN, negligible
when rise/fall time is long (>5 ns), becomes an important factor,
limiting circuit performance in the sub-nanosecond rise time region.
This paper presents simulation results of SSN in high speed digital
systems. Technical solutions for reducing SSN in the light of current
developments of advanced packaging and assembly technologies are
discussed. A quantitative comparison of SSN in digital systems
implemented with conventional as well as advanced assembly techniques is
given

ABSTRACT: The Front End Readout MIcrosystem, FERMI, is a representative of a new generation of data acquisition modules which utilizes modern design techniques to achieve a high acquisition rate together with intelligent on-line data processing. FERMI is being designed to satisfy the extreme requirements set by calorimeters in the next generation of particle physics detectors. Such detectors are being designed for the future LHC and SSC accelerators at CERN in Switzerland and at the SSC-laboratory in Texas. The calorimeters demand frequent (67 MHz for LHC, 63.5 MHz for SSC) high precision sampling of a large number of input channels (about 5x10<sup>5</sup>). Each FERMI module serves 9 channels from which samples are AD-converted, corrected and temporarily stored in a local memory. The data is also merged into a trigger sum processed by digital filters to recover time of incidence and amplitude of incoming pulses. Such data is then fed to a first-level trigger processor which screens irrelevant information. Only data that may contain interesting information is kept for further analysis. Arrays of 50000 FERMIs constitute formidable processing systems when considering the total computational power and storage capacity

ABSTRACT: The FERMI system, performing acquisition and DSP of calorimeter
data in high energy collision experiments, planned at the LHC collider
(CERN, Geneva, CH) is briefly overviewed. The system relies mainly upon
the FERMI module, a dedicated VLSI multichip device performing most of
the above functions, which is to be installed in large quantities
(around 10<sup>5</sup>) in the immediate neighborhood of the collider
itself, requiring rad-hard features. The issues for a system which
absolutely requires fault diagnosis and possibly fault tolerance are
described, with regard to the FERMI module itself

ABSTRACT: Prototypes of the \fermi{} system have been used to read out a prototype of the \atlas{} hadron calorimeter in a beam test at the CERN SPS. The \fermi{} read-out system, using a compressor and a 40 MHz sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. Signal processing techniques have been designed to optimize the treatment of \fermi{} data. The resulting energy resolution is better than the one obtained with the standard read-out.

ABSTRACT: A digital solution to the front-end electronics for calorimetric detectors at future supercolliders is presented. The solution is based on high speed converters, a fully programmable pipeline/digital filter chain and local intelligence. Questions of error correction, fault-tolerance and system redundancy are also being considered. A system integration of a multichannel device in a multichip, Silicon-on-Silicon Microsystem hybrid, is used. This solution allows a new level of integration of complex analogue and digital functions, with an excellent flexibility in mixing technologies for the different functional blocks. It also allows a high degree of programmability at both the function and the system level, and offers the possibility of customising the microsystem with detector-specific functions.
