Title:
AMPLIFICATION CIRCUIT, LASER MEASUREMENT DEVICE, AND MOBILE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2018/176289
Kind Code:
A1
Abstract:
An amplification circuit (5), a laser measurement device comprising the amplification circuit (5), and a mobile platform. The amplification circuit (5) comprises an operational amplification module (21) and an adjustment module (22). The adjustment module (22) is located on at least one of a pre-stage circuit, a post-stage circuit or a feedback circuit of the operational amplification module (21), and is used for adjusting the amplification of an input signal of the amplifier (5), so that the amplification circuit (5) enlarges energy of the input signal by using the adjusted amplification, and then outputs the signal. By means of the amplification circuit (5), the amplification of the amplification circuit (5) can be dynamically adjusted according to the energy of an input signal, so as to avoid the saturation of an operational amplifier.
