本文介绍了在UKIRT 7通道光谱仪（CGS2）上实现一种新开发的电荷放大器——积分放大器，使CGS2从传统的跨阻放大器转变为商业化的电荷集成方案。介绍了一种新的数据采集系统；新闻系统允许实现降噪算法，这是提高CGS2灵敏度的主要因素。给出了降噪算法，并给出了CGS2的系统框图。
This paper describes an implementation of a recently developed charge amplifier, called Integration Amplifier, in the UKIRT 7 channel spectrometer (CGS2), resulting in the conversion of the CGS2 from the traditional transimpedance amplifier to a commercial charge integration scheme. Also described is a new data acquisition system; the news system allowed the implementation of a noise reduction algorithm which is a mojor factor in the improved sensitivity of CGS2. The noise reduction algorithm is presented together with a system diagram of CGS2.
