摘要：

A new configuration for high input impedance bandpass, lowpass and highpass filters with low component spread using two current-feedback amplifiers is presented. It has the following features: orthogonal control of the natural frequency and quality factor by grounded resistors or capacitors, simple conversion into a voltage-controlled filter, minimum active components, low active and passive sensitivities, low component spread suitable for high-Q applications and low output impedance. Experimental results are given to demonstrate the feasibility of the proposed circuits.
