Abstract

This paper presents a power-efficient receiver topology for short-range LiDAR sensor applications by utilizing a 180-nm CMOS technology. The proposed design includes a fully differential transimpedance amplifier (TIA) with on-chip avalanche photodiodes and a time-to-voltage (T2V) converter. Post-layout simulations reveal that the T2V converter handles the input photocurrents from 40 μApp to 5.8 mApp for the detection range as short as 30 centimeters. The single-channel LiDAR receiver consumes 10 mW from a single 1.8-V supply and covers a detection range of 0.3 to 22.8 meters. The whole 4x6 channel optoelectronic receiver array occupies an area of 1.5 x 2.0 mm², including I/O pads.
