提出了采用第二代电流传送器构成的电压模式三输入、单输出多功能通用双二阶滤波电路 ,该电路通过选择不同的输入信号 ,可在输出端得到电压模式二阶低通、高通、带通、陷波和全通五种滤波功能。每种滤波功能的滤波器的固有角频率ωP和品质因素 QP可实现正交调节 ,所有滤波器都具有低的无源和有源灵敏度。 A voltage mode three-input and one-output multi-function universal biquad filter with a second-generation current transmitter is proposed. By selecting different input signals, the voltage mode second-order low-pass filter, high-pass filter, Band pass, notch and all-pass five filtering functions. The filter’s natural angular frequency ω P and quality factor Q P for each filter function allow for quadrature regulation and all filters have low passive and active sensitivity.
