本文提出了一种减少电容分布和总电容的高Q和/或高f_s开关电容(SC)带通滤波器。在传统的双二次SC滤波器结构中,引入部分正反馈并改变前馈网络可使总电容和电容分布得到大幅度的减少。举例说明了二阶高Q(=50)SC带通滤波器设计,并比较了不同滤波器结构的性能参数。 This paper presents a high-Q and / or high-f_s switched-capacitor (SC) band-pass filter that reduces capacitance distribution and total capacitance. In the traditional double-quadratic SC filter structure, the introduction of partial positive feedback and the change of feedforward network can make the total capacitance and capacitance distribution can be greatly reduced. The second-order high-Q (= 50) SC bandpass filter design is illustrated and the performance parameters of different filter structures are compared.
