一、前言尽管线性集成电路的种类及元件多,功能复杂,制造困难,但它在计算机、控制系统、通信设备及各种测量系统等许多电子学设备中得到广泛的应用。因此,为了制造高性能和大规模化的线性集成电路,作了许多努力,到目前已有了许多新进展。当前,在线性单块集成电路中出现的新途径有双极-MOS相结合的和用注入逻辑构成的两种。在同一芯片上作双极与MOS器件可以不影响两种器件的性能,而且可以利用它们各自的优点来改善线性集成电路的性能,降低功耗,提高集成度,并可实现大规 I. INTRODUCTION Although linear integrated circuits have many types and components, complicated functions and difficulties in manufacture, they are widely used in many electronic devices such as computers, control systems, communication devices and various measurement systems. Therefore, many efforts have been made to manufacture high-performance and large-scale linear integrated circuits, and many new developments have been made so far. Currently, new ways of emerging in linear monolithic integrated circuits are bipolar-MOS combined and injected logic. Bipolar and MOS devices on the same chip can not affect the performance of the two devices, and can take advantage of their respective advantages to improve the performance of linear integrated circuits, reduce power consumption, improve integration, and can achieve large
