中文摘要：
常规的粗粒度可重构模拟电路灵活性不高,而且可重构模拟单元（CAB）结构较为复杂。针对此类问题,该文改进并设计了一种新的基于OTA的可重构模拟电路。该电路设计方案降低了CAB的复杂度,提高了CAB的使用效率。该文方法的有效性通过3个模拟设计实例（二阶低通滤波器、高通滤波器和三阶巴特沃思低通滤波器）的设计加以验证。实验结果表明,所提出的方法正确有效,可以较好地兼顾CAB资源与所要求功能的平衡。
英文摘要：
The conventional coarse-grained reconfigurable analog circuits have bad flexibility, and the reConfigurable Analog Block （CAB） structure is complicated. In order to solve such problems, a new OTA-based reconfigurable analog circuit is presented in this paper. In this circuit scheme, the complexity of CAB is reduced and the CAB utilization rate is increased. To verify the effectiveness, three examples of analog circuit design （a second-order low pass filter, a second-order high pass filter and a low-pass third-order Butterworth filter） are presented. The experimental results indicate that the proposed circuits is effective and feasible, which make a better balance between circuit resources and functions.
