资料介绍

根据微弱信号检测技术和电路低噪声设计基本原理,结合阵列感应仪器本身的接收信号强度微弱、干扰严重等特性,分析阵列感应测井仪器前置放大电路的低噪声单位增益缓冲级模块、第1级放大模块、第2级放大模块及温度补偿模块的设计重点和难点;对电路进行时域、频域和噪声特性仿真;对其温度性能进行实际测试,得出其主要的性能指标。分析前置放大电路容易出现的故障并提出解决措施。验证该前置放大器的可行性和实用性。

According to the weak signal detecting technology, low noise design principles for circuits and features of weak signal receiving and strong noise of multi-frequency array induction logging tool, emphasized are design key and difficult points of unit plus cushion model, first amplification model, second amplification model and temperature compensation model in the pre- amplifying circuit; Stimulated are characteristics of the circuit in time domain, frequency domain and noise; Tested is the circuit temperature characteristic in practice. The circuit's key performance specification has been achieved. Analyzed are failures of the circuit and proposed are their solutions. Verified are the feasibility and practical applicability of this pre-amplifie...
