Fab-to-fab and run-to-run variability in 130 nm and 65 nm CMOS technologies exposed to ultra-high TID

Jean-Michel Sallese, Adil Koukab, Gennaro Termo, Stefano Michelis

The discovery of a large fab-to-fab variability in the TID response of the CMOS technologies used in the design of ASICs for the particle detectors of the HL-LHC triggered a monitoring effort to verify the consistency of the CMOS production process over ti ...

Time-resolved multi-gate ion sensitive field effect transducer and system and method of operating the same

Jean-Michel Sallese, Adil Koukab

A time-resolved multi-gate ion sensitive field effect transducer, including a silicon layer, a P-doped region in the silicon layer and a first electrode in electric connection with the P doped region, a N-doped region in the silicon layer and a second elec ...

New architecture for the analog front-end of Medipix4

Jean-Michel Sallese, Adil Koukab, Viros Sriskaran

The Medipix4 chip is the latest member of the family of Medipix pixel detector readout chips aimed at high rate spectroscopic X-ray imaging. Unlike its predecessors, it will be possible to tile the chip on all 4 sides permitting seamless large area coverag ...

A Dual-Edge Pulsewidth Modulator for Fast Dynamic Response DC-DC Converters

Maher Kayal, Adil Koukab, Giacomo Ripamonti, Stefano Michelis, Federico Faccio

Voltage regulator modules are dc-dc converters that power modern microprocessors. They must exhibit a fast dynamic response, in order to achieve satisfactory regulation performance in spite of the rapid load current variations. The pulsewidth modulator is ...

Computing the Impact of White and Flicker Noise in Continuous-Time Integrator-Based ADCs

Maher Kayal, Adil Koukab, Paul Stanislas Gosselin

From first-order incremental Sigma Delta converters to controlled-oscillator-based converters, many ADC architectures are based on the continuous-time integration of the input signal. However, the accuracy of such converters cannot be properly estimated wi ...

Silicon-on-Insulator Technology for Bioluminescence Imaging and Application to a Switching Photodetector

Maher Kayal, Adil Koukab, Denis Sallin, Nisrina Abdo

This paper analyzes some advantages of Silicon-on-Insulator (SOI) based photodetectors for bioluminescence imaging. It shows that SOI based sensors not only solve the bulk carriers problem, it can also act as a very selective spectral filter by acting as a ...

A dynamic operation of a PIN photodiode

Alexander Tagantsev, Maher Kayal, Adil Koukab, Serguei Okhonin, Maxim Gureev, Alexander Kvasov, Marc Pastre, Denis Sallin

Traditionally, photodiodes operate at static reverse bias, and incident light intensity is obtained from the relatively week photocurrent. In this paper, we introduce a different concept of photodiode function: the photodiode is used in a dynamic regime wh ...
