摘要
提出了一种实现高输入阻抗电压模式滤波器的新电路。该电路使用一个CCII(第二代电流传输器)和最少量的RC元件实现一阶低通、一阶高通及二阶带通滤波器。一阶滤波器仅含3个接地RC元件,二阶滤波器含4个RC元件,其中电容均接地。
A novel filter with a high input impedance is presented,which is constructed by a single CCII and the fewest RC elements.By using the new circuit,a first order lowpass,highpass filter and second order bandpass filter can be realized.The first order filter only contains three grounded RC elements,and the second filter contains four RC elements where the capacitors are all grounded.The active and passive sensitivities of the filters are given,along with their PSPICE simulation results.
