This paper presents a compact CMOS tunable positive and negative active inductor simulator (AIs), positive capacitance and resistance multiplier and negative capacitance and resistance simulator. The proposed design use only one analog building block (ABB) and three passive elements. Applications in the design of different types of tunable filters and parasitic compensation are also presented. The functionality of the design is confirmed using Tanner Tspice in 0.18µm TSMC CMOS technology. Simulation results indicate that the proposed design is superior to previous arts in many aspects.
