A Novel Compact and Tunable Positive and Negative Impedance Simulator
and Multiplier
Abstract
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.
