To improve upon traditional active inductors based on current-reuse structures，a novel active inductor with low power consumption， low noise， and independently tunable inductance(L) and quality factor(Q) is proposed. The design primarily consists of a gain-enhanced common-source(CS)– common-gate(CG)composite negative transconductor(NT)with a voltage tuning terminal，a CG positive transconductor(PT)，a noise suppression branch，and an active feedback amplifier. The NT and PT are connected in a current-reuse configuration，which enables inductive behavior while reducing power consumption and improving the Q factor. To further suppress noise， a noise suppression branch is introduced at the gate of the CG PT. Additionally，an active feedback amplifier with a voltage tuning terminal is added to the feedback path between the PT and NT to enhance the Q factor and compensate for variations in the Q peak caused by L tuning. This topology allows for independent tuning of the inductance value relative to the Q factor at a fixed frequency，while maintaining a nearly constant Q peak across different frequencies.The circuit also exhibits low power consumption and low noise. Fabricated using a 0. 18-μm CMOS process，the inductance can be tuned from 258–469 nH，representing a tuning range of 83. 7%，with only a 1. 4% variation in Q at a high frequency of 2. 75 GHz. At operating frequencies of 2. 1，2. 5，and 3.2 GHz，the Q peak values are 327，329， and 328，respectively，showing a variation of just 0. 3%. The noise is 2. 99 at 1 GHz and 1. 74 at 2. 75 GHz. The total power consumption is only 0. 96 mW.
