Abstract
In this paper, we analyze the effect of opamp finite gain-bandwidth-product (GBW) on the performance of generalized impedance converter (GIC)-based frequency-dependent negative resistance (FDNR) realizations. Their use for realizing a resonator as well as second-order low-pass filter and a high-order filter is also investigated. The effect of finite GBW of the opamps on the pole-frequency, pole-Q and transmission zeroes of resonators and low-pass filters is presented together with simulation results.
