A Fully Integrated Active Inductor with Independent Voltage Tunable Inductance and Series-Loss Resistance
نویسنده
چکیده
A fully integrated GaAs MESFET active inductor is presented in this paper with independent voltage tunable inductance and series-loss resistance. The measured inductance is tunable from 65 to 110 nH in the frequency range from 100 MHz to 1.0 GHz. The measured loss resistance is independently tunable over a 5.6to+20.8range corresponding to a 0.26 and 0.65 V change in dc tuning voltages, respectively.

Monolithic Tunable Active Inductor with Independent Q Control
A 1.1-GHz fully integrated GaAs MESFET active inductor is presented in this paper. Both the inductance and loss resistance are tunable with the inductance independent of series loss tuning. The measured loss resistance is tunable over a 10to +15range with a corresponding change in inductance of less than 10% at 100 MHz and less than 4% for frequencies above 500 MHz. The inductance is tunable fr...
متن کاملCancellation of Series-Loss Resistance in UWB Active Inductors using RC Feedback
One of the most important features of the Active Inductors (AIs) is their input equivalent resistance, namely series-loss resistance, which should be low enough to have a high Quality Factor (QF). Most of the previous methods by this goal did not yield a high enough QF. This paper presents a new method, namely applying an RC feedback, to cancel series-loss resistance entirely. As the RC fee...
