Correction of the Attenuation of the Low-pass Biquad in the Current Mode Based on Prototype in Voltage Mode
نویسندگان
چکیده
The second order Sallen-Key low-pass filter structures have one disadvantage in the voltage and current mode, it is a decreasing of the attenuation in the stopband. This fact is caused by losses of the amplification factor of active elements at high frequencies. Some solutions of this problem had been already published for circuits working in the voltage mode. This article presents one of the possible solutions of this problem for circuits working in the current mode.
