An analogous front - end - receiver with a large dynamic range for long - range - lidar

摘要

In the case of certain embodiments, a front - end - receiver is provided, which contains a transimpedance amplifier (tia), which is designed for converting an input current which is applied to an input port in an output voltage, and a first adaptive limiter circuit, which via a diode paths coupled at the input port and is designed, in response to a limiter circuit applied to the first adaptive a maximum value of a limiting circuit input voltage of the tia to an externally applied to limit the limiting voltage, so that the tia not too strongly is saturated. In some cases, the first adaptive limiter circuit the maximum value of the input voltage of the tia limit in such a way that the tia as close as possible to the saturation threshold value voltage of the tia operates.n="40"
