Original Abstract

Till now used tunable band-reject filters with higher Q-factor value and with two or more operational amplifiers have a serious dynamic range limitation. It is caused by Q-times higher maximum transfer factor to other operational amplifier outputs. A new design of 2nd order notch tunable filter for ARC and SC realization without dynamic range reduction is proposed in this paper. It is solved by independent setting of maximum transfer factors to other operational amplifier outputs. The two examples of 2nd order BR filters for ARC and SC realization are designed in this way.
