该论文对第四阶SC LPF的传输函数进行了修正，并探讨了其带宽可扩展性。

59.2 dB SFDR, 0.5-to-10 MHz bandwidth

SC LPF传输函数带宽可扩展性电路设计修正

▸创新点1：修正了传输函数的错误（方法创新）。通过更正z域传输函数中的符号错误，确保了滤波器设计的准确性，提高了电路的性能指标，如SFDR（无杂散动态范围）和带宽可扩展性。

▸创新点2：探讨了带宽可扩展性（系统创新）。研究了滤波器在0.5到10 MHz范围内的带宽可扩展性，为不同应用场景提供了灵活的设计方案，增强了电路的适用性。

▸创新点3：提出了新的电路设计方法（电路创新）。采用回收SC缓冲器双二阶滤波器结构，优化了电路面积和功耗，实现了0.02 mm²的小面积设计和59.2 dB的高SFDR性能。

▸创新点4：改进了滤波器性能指标（性能创新）。通过修正传输函数和优化电路设计，显著提升了滤波器的SFDR和带宽可扩展性，使其在低功耗和小面积应用中表现出色。
