ASIC

Oral

The high multiplicity of neutrino events in the DUNE Liquid Argon Near Detector (ND-LAr) requires a high-fidelity 3D-imaging technology capable of handling complex topologies. LArPix is a pixelated charge readout system for Liquid Argon Time Projection Chambers (LArTPCs) based on a cryogenic-compatible ASIC, providing a fully-integrated analog-to-digital signal pathway within the LAr. A...

ASIC

Oral

The IGNITE project develops technical solutions for the next generation of trackers at colliders. The final ASIC, the IgnitER, is being designed to have pitch of 45 µm and time resolution on the full chain (sensor to TDC) below 50 ps.
We present measurements aimed at characterizing the Ignite64, a prototype featuring a matrix of 64x64 pixels and a pitch of 55 µm. Tests are made both with and...

The CALOROC1B ASIC is a 36-channels ASIC designed to read out large SiPMs (up to 10 nF) for the ePIC calorimeter at EIC using a streaming readout. This work presents the measurement results of the chips received in April 2026. These measurements confirm the linearity and reliability of the gain-switching mechanism, which enables the ASIC to achieve a large dynamic range (from 150 fC up to 1.5...

131. A 64-channel ASIC for the readout of the MicroMega detectors of the AMBER experiment

ASIC

Oral

The ToRA ASIC is the first prototype for the readout of the MicroMega detectors for the AMBER experiment upgrade.
Its 64 channels provides 4 programmable gain values and shaping times. It measures the arrival time and the time over threshold of the shaped signal. Moreover, it can also measure the peak time, store the peak value and convert it to digital via a simple single-ramp ADC. The time...

With increasing digital processing complexity and development costs, the next generation of front-end detector ASICs will greatly benefit from programmable embedded architectures. This work introduces ROSA, an embedded microcontroller on the Picopix chip, for the LS4 upgrade of the LHCb VELO detector. ROSA acts as an on-chip master on the slow control configuration bus of Picopix and can be...

67. A Pre-Silicon Flow for IR-drop Induced Jitter Simulation

Mr David Peninon Herbaut (CERN)

ASIC

Oral

Dynamic IR-drop-induced jitter is a critical limitation in modern high-speed ASICs, affecting both precision timing and high-rate data transmission. Switching activity causes transient supply voltage variations that modulate gate delays and translate directly into timing uncertainty. Accurately estimating this effect at the pre-silicon stage remains an open challenge, particularly for complex...
