Abstract
Techniques to adjust a gain of an analog-to-digital converter circuit (ADC) and/or an ADC full scale from one sample to the next of an analog input signal to compensate for the signal loss over distance, which can increase an effective dynamic range of the system. The benefit of compensating for the signal loss due to distance is that a data interface between the ADC of the receiver of the LIDAR system and a signal processor no longer needs to support the dynamic range from the range specification.
