Active-R realization of bilinear RL impedances and their applications in a high-Q parallel resonator and external capacitorless oscillator

Realization of bilinear RL impedances use only one operational amplifier (OA) and one or two resistors is proposed. These are based on the single-pole model of the OA. Applicabilities of these one-port active-R grounded inductances in a parallel capacitor tuned high-Qresonator and in a new external capacitorless sine-wave oscillator are also reported tosether with experimental verification.
