Bode-Type Amplitude Equalizers Using Current Feedback Operational Amplifier
Ahmed M Soliman

New active RC Bode-type variable equalizers using current feedback operational amplifier (CFOA) are introduced. The proposed equalizers can operate at much higher frequencies than the classical Voltage Operational Amplifier (VOA) based variable amplitude equalizers. Spice simulation results using technology SCN 0.5 feature size 0.5 μm from MOSIS vendor: AGILENT are included to confirm the practicality of the proposed circuits and detailed comparisons of the VOA based equalizers and the CFOA based equalizers are included.

Keywords: Current Feedback Operational Amplifier, Variable Equalizers.
