Abstract :
Integrated CMOS and BiCMOS timing detectors have been designed for the receiver of a portable laser radar. The timing detectors produce accurately timed logic level pulses from noisy analog pulses, whose amplitude varies in a wide range. The distance measurement result of the designed BiCMOS (CMOS) detector varies +/-4 mm (+/-9 mm) with an input amplitude range of 55 mV-3.3 V (0.5 V-2.2 V). The single shot resolution with SNR=250 is better than 6 mm (10.5 mm)
