Assignee: BEIJING VOYAGER TECHNOLOGY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 12:
13. A copackaged frontend of a receiver for an optical sensing system, comprising:
a photodetector configured to receive an optical signal and convert the optical signal to an electrical signal; and
a readout circuit configured to generate a readout signal based on the electrical signal received from the photodetector,
wherein the photodetector and the readout circuit are disposed in a same substrate and the substrate is connected to the readout circuit through one or more bonding wires, and
wherein the photodetector and the readout circuit are stacked over one another on the substrate, and are connected through one or more through silicon vias (TSVs) in a three-dimensional (3D) structure.
