A receiver channel with a leading edge timing discriminator for a pulsed time-of-flight laser radar
An integrated receiver channel with a wide dynamic range for a pulsed time-of-flight (TOF) laser rangefinder has been designed and tested. The circuit uses leading edge timing discrimination. The bandwidth of the receiver channel is 250 MHz and the maximum transimpedance 40 k&937;. The single-shot distance measurement accuracy is 65 mm, taking into account walk error (input signal amplitude varies in the range from 1 to 4000) and jitter (+/-3&963;).
