Current Mode Filters Using Current Feedback Amplifiers with Negative Impedance (Resistance)

Abstract:

This paper describes a current mode filter using two current feedback amplifiers (CFA's). One CFA is used to simulate a negative resistor. The proposed circuit is very useful for low as well as high frequency applications. Circuit is simple and canonic. The use of grounded capacitors in the design make it suitable for implementation in CMOS technology.
