For the potential use in future high luminosity application in HEP (e.g. the LHC
upgrade), we evaluated the radiation hardness of a candidate technology for the
front-end of the readout ASIC for silicon strip detectors. The devices were test
transistors of various geometries manufactured in the first generation, IBM SiGe 5HP
process. Current gain as a function of collector current has been...

The ALICE TPC Front End Electronics will be operated in a radiation field of up to
800 hadrons/cm2sec. SRAM-based FPGAs are used on the Front-End Cards (FEC) and the
Read-out Control Units (RCU). Several irradiation tests of all components on the
cards have ensured that the components selected are able to withstand the radiation
environment, but have also shown that single event upsets...

We have developed a radiation-tolerant Low Drop-Out (LDO) voltage regulator for
applications in High Energy Physics experiments. The regulator outputs a fixed
voltage of 2.5V, it provides a maximum current of 300mA with a drop-out as low as
150mV. The circuit incorporates over-current, over-voltage and over-temperature
protection, and it can be disabled via a dedicated input pin....

The ALICE TRD has over 1,2 million analog channels that will be
digitized at 10MSPS with 10-bit resolution. We have developed a
TRAcklet Processor (TRAP) ASICs implementing 22 extra low power
ADCs, digital filters, four RISC processors with shared memory, slow
control serial interface and fast parallel 4-in 1-out readout
tree ports.
Together with the preamplifier chip they build a...
