Novel electronically controllable grounded series/parallel lossy inductor simulator configurations.

The objective of this research paper is to propose novel series/parallel lossy grounded inductor simulation configurationswith the minimum requirement of active and passive elements. Each presented simulator circuit employs one voltage differencing transconductance amplifier(VDTA) along with a single capacitor connected to ground. All the presented simulators are purely resistorfree realizations with electronic tuning facility and do not need any requirement of component matching. In all the proposed configurations, full utilization of the input stage of employed VDTAs has been achieved, except forone series LR circuit. The performance of the presentedsimulation configurations is also studied under non-ideal conditions as well as with the terminal parasitic impedances of VDTA. The behavior of the proposed series/parallel R-L impedance simulation circuits is confirmed by some application examples. The theoretical analysis has been validated by running SPICE simulations with TSMC CMOS 0.18 μm process parameters. [ABSTRACT FROM AUTHOR]
