通常，需要施加相位差为90度的4个正弦波来测量RC多相滤波器的频率特性。另一方面，已知通过使用由简单的数字电路产生的4个方波代替正弦波可以获得相同的结果。本文首先简要介绍了其测量方法。其次，给出了集成电路的设计。最后给出了版图设计，验证了本文工作的有效性。
Generally, it is required to apply 4 sinusoidal waves whose phase difference are 90 degrees to measure the frequency characteristics of an RC polyphase filter. On the other hand, it is known that the same result can be obtained by using 4 square waves generated by a simple digital circuit instead of sine waves. In this paper, first, its measurement method is briefly introduced. Second, the circuit design for its integration is presented. Finally, the layout design is shown, and validity of this work is conformed.
