Abstract :
Novel voltage mode filters based on a new architecture for a current feedback amplifier are proposed in this paper. The new biquads are attractive because they exhibit low Q- and ω0-variability due the constant bandwidth of the new amplifier used. Theoretical results as well as experimental results obtained using an AD844 and a 741 operational amplifier are presented.
