摘要
介绍了一种新型电荷放大器设计方法和电路.通过对电荷放大器电路的理论研究,提出用TL081取代大量的分立元件进行电荷放大器的优化设计方案,提高了电路的集成度,使其具有体积小、功耗低、寄生因素少和抗干扰性能强的优点.通过与标准电荷放大器的比较测试实验,验证了该电路的可行性和可靠性.
A novel charge amplifier is designed and its circuit is described in the paper. Through theoretical research on the charge amplifier, an optimization design for charge amplifier is proposed which uses TL081 to replace a large number of discrete components. The design not only improves the integration of the circuit, but also has some extra merits, including smaller volume, lower consumption, less autoeciousness and stronger resistance to interruption. Compared with the standard charge amplifier, the feasibility and reliability of the system are confirmed.
