LiDAR remote sensing of the atmosphere requires a photons detection chain with a high sensitivity and a high dynamic range associated with a good temporal resolution. To meet these requirements, a specific CMOS read out circuit (ROIC) has been studied, design and realized at CEA/Leti within the frame of the H2020 project HOLDON. This ROIC is based on a CTIA amplifier with four different current/voltage conversion gain thanks to capacitance ranging from 10 fF to 10 pf. Other functionalities like on chip sampling, auto-reset or programmable low pass filtering have been implemented to optimize the detector for different measurement chain. Based on this circuit architecture, two versions of the ROIC with different way to connect the circuit to the photodiodes have been manufactured and tested. The first one is design to be directly hybridized to a small array of photodiodes with a format imposed by the ROIC design in term of pixel pitch and array size. For the second ROIC version, the photodiode array is hybridized to an interconnection circuit used as a fan-out of electrical connections to a bonding pad. This module is then wire-bonded to the ROIC to get the final detector assembly. This configuration allows us to couple the ROIC with different APD geometry adapted to a specific application need. The performances of one of the first hybridized devices were previously presented during ICSO 2020[1]. For this review, we focus on the second version of the ROIC. The tested detector module is made of an array of 76 HgCdTe APD in parallel with a pixel pitch of 15 µm. The array forms a 150 µm diameter macro-photodiode. The device was tested at 78K within a liquid nitrogen cooled cryostat. Under photon flux, we have obtained a linear response of the device with an incoming flux varying over more than six orders of magnitude without varying the APD gain. This wild dynamic is associated with a high sensitivity with a noise standing below the unique photon. The response to a brief laser pulse gives a rise time ranging from 175 ns for the highest CTIA gain to 6 ns for the lowest CTIA gain.
