Low power discriminator for ATLAS pixel chip

M Karagounis, J D Schipper, F Gensolen, D Fougeron, D Gnani, A Rozanov, R Kluit, R Elledge, R Beccherle, M Barbero, T Hemperek, A Mekkaoui, M Garcia-Sciveres, S Dube, A Kruth, M Menouni, V Gromov & D Arutinov
The design of the front-end (FE) pixel electronics requires low power, low noise and low threshold dispersion. In this work, we propose a new architecture for the discriminator circuit. It is based on the principle of dynamic biasing and developed for the FE chip of the ATLAS pixel upgrade. This paper presents two discriminator structures where the bias current depends on the presence of a signal at the input of the discriminator. Since the activity...

Time Resolution of a Few Nanoseconds in Silicon Strip Detectors Using the APV25 Chip

M Pernicka, C Irmler & M Friedl
The APV25 front-end chip for the CMS Silicon Tracker has a peaking time of 50 ns, but confines the signal to a single clock period (=bunch crossing) with its internal “deconvolution” filter. This method requires a beam-synchronous clock and thus cannot be applied to a (quasi-) continuous beam. Nevertheless, using the multi-peak mode of the APV25, where 3 (or 6,9,12,...) consecutive shaper output samples are read out, the peak time can be reconstructed externally with...

Transmission-Line Readout with Good Time and Space Resolutions for Planacon MCP-PMTs

G Drake, C Ertley, F Tang, K Byrum, H Frisch, J-F Genat, J Anderson & E May
With commercially-available multi-anode microchannel plate photomultiplier tubes (MCP-PMT) and electronics, resolutions significantly better than 10 psec have been achieved in small systems with a few readout channels[1,2]. For large-scale time-of-flight systems used in particle physics, which may cover tens of square meters, a solution must be found with a manageable number of electronics channels and low total power consumption on the readout electronics without degrading the system timing resolution. We present here the design of...

Optoelectronics, a global telecom carrier’s perspective

J Batten
This paper summarises the current approaches to high speed optical transmission design. Cable & Wireless operates a large global optical transmission network, with the main purpose of serving the bandwidth market and of providing connectivity for its Internet Protocol data networks. In long haul spans, dense wavelength division multiplexed systems with aggregate capacities of 1 Tbit/s per fibre are deployed. The increase in bandwidth requirement is driving the need for more complex technologies that deliver...
