Description
Reconstructing particle tracks in future high-luminosity collider experiments is expected to be challenging. AC-LGAD is one of the candidates to solve the problem using excellent spatial and timing resolution.
In multi-channel readouts, low-power consumption pre-amplifier and digital circuit are required because the number of readout circuit increases with the number of AC-LGADs channels. The timing resolution of AC-LGADs is affected by electronic noise. Therefore, developing a low-noise readout ASIC for multi-channel readout of AC-LGADs is crucial to further improve the timing resolution.
Si-Ge (Silicon-Germanium) based ASICs are characterized by low-power consumption, low-noise and high-speed operation. So, I will present the performance evaluation of Si-Ge based ASICs using signals from AC-LGADs, in response to infrared pulsed laser and β-source.
