一个新的低灵敏度高Q开关电容双二次实现

A Novel High Q Switched-Capacitor Biquad Realization with low Sensitivity

本文提出了一个新的低灵敏度高Q开关电容(SC)双二次,即使在高Q和大采样频率指标下,它也有可能获得小总电容。本文也给出了由该双二次实现的二阶低通、带通、高通和陷波滤波器。

A novel switched-capacitor (SO biquad for realizing high Q values is presented. The biquad has low sensitivity and can also obtain small total capacitance even though the high Q value and large sampling frequency specifications are given. The second-order lowpass, bandpass, highpass and notch filters realized by mears of this biquad ate given.
