Design and Performance Analysis of Active Inductor with Low Voltage and High Q factor

Two Active Inductor design has been designed and simulated using UMC 0.18μm technology and Cadence Virtuoso. Active Inductor Design I show inductive behavior up to 2.75 GHz and more suitable for voltage controlled oscillator. It also achieves a high-value Q of 700 and draws the current of 116 uA at 750m bias voltage. Besides, a novel approach to tune the inductor is investigated using Active Inductor Design-II. Use of bulk or body bias voltage can tune the inductance. The results of the proposed design-I are discussed and compared. The approach is validated by using the Simulation result.
