A Laser Scanner Chip Set for Accurate Perception Systems
This paper presents an integrated receiver channel and an integrated time-to-digital (TDC) converter fabricated in a 0.35 μm SiGe BiCMOS and in 0.35 μm CMOS technologies, respectively, that give the required performance for a pulsed time-of-flight (TOF) laser radar to be used in a laser scanner in automotive applications. The receiver-TDC chip set is capable to measure the positions and widths of three separate successive timing pulses with sub-ns level precision in a wide dynamic amplitude range of more than 1:10.000.
