/ Piller, M (CERN ; Graz, Tech. U.) ; Ballabriga, R (CERN) ; Bandi, F (CERN) ; Campbell, M (CERN) ; Deutschmann, B (Graz, Tech. U.) ; Fernández-Tenllado, J M (CERN) ; Gascon, D (Barcelona U.) ; Gomez, S (Barcelona, Polytechnic U. ; Barcelona U.) ; Michalowska-Forsyth, A (Graz, Tech. U.) ; Mauricio, J (Barcelona U.) et al.
The field of detector readout electronics for precise timing has experienced a remarkable surge of interest due to its diverse range of applications in nuclear medicine such as Positron Emission Tomography (PET), High Energy Physics (HEP), Time-of-Flight (ToF) mass spectrometry and many other fields. This growth can be attributed to rapid advancements in photodetectors, particularly the silicon photomultiplier (SiPM), which has demonstrated exceptional suitability for these applications, owing to its ability to generate signals with unprecedentedly fast rise times.

20-ps resolution Clock Distribution Network for a fast-timing single photon detector
/ Egidos, N (CERN) ; Ballabriga, R (CERN) ; Bandi, F (Seville U.) ; Campbell, M (CERN) ; Gascon, D (ICC, Barcelona U.) ; Gomez, S (ICC, Barcelona U.) ; Fernandez-Tenllado, J M (CERN) ; Llopart, X (CERN) ; Manera, R (ICC, Barcelona U.) ; Mauricio, J (ICC, Barcelona U.) et al.
The time resolution of active pixel sensors whose timestamp mechanism is based on Time-to-Digital Converters is critically linked to the accuracy in the distribution of the master clock signal that latches the timestamp values across the detector. The Clock Distribution Network that delivers the master clock signal must compensate process-voltage-temperature variations to reduce static time errors (skew), and minimize the power supply bounce to prevent dynamic time errors (jitter).

Optimal design of single-photon sensor front-end electronics for fast-timing applications
/ Fernández-Tenllado, J M (CERN) ; Ballabriga, R (CERN) ; Campbell, M (CERN) ; Gascón, D (ICC, Barcelona U.) ; Gómez, S (ICC, Barcelona U.) ; Mauricio, J (ICC, Barcelona U.)
In the study presented, we focus on the contribution of the front-end electronics to the single-photon time resolution, particularly for Silicon Photomultipliers. We investigate from a simple model for current sensing front-ends, the impact of parameters such as detector capacitance, parasitic inductance in the interconnection and input impedance (equivalent RLC network) in the slew-rate of the signal on one side, and the interaction of series and parallel noise with the detector capacitance on the other side.
