A 4-Tap CMOS lock-in modulator with Anti-Interference and Background Canceling for Solid-State Long-Range LiDAR

In this paper, we present a 4-Tap CMOS lock-in modulator designed for solid-state long-range LiDAR. The proposed lock-in modulator is based on a pinned photodiode structure with non-uniform doping and double TX structure for each tap. With a specially designed high dynamic range, the pixel array is...

Abstract In this paper, we present a 4-Tap CMOS lock-in modulator designed for solid-state long-range LiDAR. The proposed lock-in modulator is based on a pinned photodiode structure with non-uniform doping and double TX structure for each tap. With a specially designed high dynamic range, the pixel array is able to get 3D depth information of objects for both long and short range with anti-interference and background canceling.
