In this paper, a new CMOS grounded positive tunable inductor simulator based on using two simple CMOS transconductors and an inverting amplifier is presented. The introduced inductor simulator uses a grounded capacitor; accordingly, it is suitable for integrated circuit (IC) fabrication. In addition a CMOS circuit for realizing negative tunable resistor which can be used for parasitic cancellation in inductor simulators and consequently enhancing their frequency performances is developed. A novel method for providing high-frequency performance improvement of simulated inductors is also introduced. Simulation and experimental results are given to demonstrate the performance of the developed inductor simulator and validity of the proposed frequency performance improvement method.
