Joo, Ji-Eun Lee, Myung-Jae Park, Sung Min 2024-01-19T10:01:02Z 2024-01-19T10:01:02Z 2023-05-11 2023-03 1530-437X https://pubs.kist.re.kr/handle/201004/113903 article presents an optoelectronic receiver IC with on-chip avalanche photodiode (APD) realized in a 180-nm CMOS process for the applications of indoor-monitoring light detection and ranging (LiDAR) sensors. As an on-chip optical detector, a CMOS p+/n-well APD is inte-grated, thereby enabling to avoid unwanted signal distortion from bond-wires and electrostatic discharge (ESD) protection diodes. Various circuit techniques are exploited in this work, including the dual-feedback folded-cascode differential tran-simpedance amplifier (DFD-TIA) to achieve fully differential signaling from the input stage, an active single-to-differential (ASD) converter to minimize the inherent mismatches of the preceding DFD-TIA, a cross-coupled inverter-based postam-plifier (CI-PA) to improve the symmetry of the output voltage swings, and a two-stage differential amplifier with negative impedance compensation (TDA-NIC) to obtain gain-boosting transimpedance gain, 577-MHz bandwidth, 15.4-pA/vHz noise current spectral density, 4.18-mu Appminimum detectable and wide bandwidth characteristics. Measured results of the proposed optoelectronic receiver IC demonstrate 87-dB.Q signal that corresponds to the maximum detection range of 10 m, and 50.6-mW power dissipation from a 1.8-V supply. Optical measurements utilizing an 850-nm laser diode with the average power of 10 mW reveal that the proposed optoelectronic receiver IC successfully recovers narrow 1-ns light pulses with the full-width at half-maximum (FHWM) of 840 ps even at the short distance of 50 cm. Hence, this work provides a potential solution for low-cost, low-power short-range LiDAR sensors.
