一、引言随着大规模集成电路技术的高速发展,经典的线性定常电路理论开始转向用非线性的时变电路的分析和综合;连续模拟域处理也扩展到了离散数字域,由此导致了一些新型电路器件的出现。开关电路技术就是其中的一个分支。用 MOS 模拟开关(MOS 传输门)、电容、运算放大器为基本元件集成在一芯片上的单片开关电路滤波器(Switched Capacitor Filter)克服了由分立元件组成的滤波器的体积 I. INTRODUCTION With the rapid development of large-scale integrated circuit technology, classical linear steady-state circuit theory has turned to the analysis and synthesis of non-linear time-varying circuits. The continuous analog domain processing has also been extended to the discrete digital domain, resulting in some Emergence of new circuit devices. Switching circuit technology is one of the branches. The Switched Capacitor Filter, which integrates MOS analog switches (MOS transmission gates), capacitors, and op amps into a single chip, overcomes the problem of a filter consisting of discrete components
