一、前言运算放大器组件由于其开环增益高、漂移小、输入阻抗高以及使用方便等优点,在电子技术领域里得到了广泛的应用。但是,由于常用的运算放大器组件(以下简称“组件”)几乎全都是作成低功耗的,因此,其负载能力十分有限。输出电压幅度也受供电限制,不能太大。组件这一“先天”的不足大大限制了它的应用。这样,使用者常常会面临提高其功率输出,扩展其输出电压幅度的任务。要提高输出功率已有许多方便可行的方法,这里不再赘
I. Introduction Operational amplifier components due to its high open-loop gain, small drift, high input impedance and ease of use, etc., in the field of electronic technology has been widely used. However, since commonly used operational amplifier components (hereinafter referred to as “components”) are made of low power consumption, their load capacity is very limited. Output voltage range also limited by the power supply, not too big. This “inherent” component of the component greatly limits its application. In this way, users often face the task of increasing their power output and expanding their output voltage amplitude. To improve the output power has many convenient and feasible method, here no more
