Loss compensation in RF CMOS active inductor using a capacitor

Abstract

Loss compensation in a RF CMOS active inductor with using a capacitor is proposed. This simple compensation technique yields a negative conductance characteristic that can compensate for the constant internal loss of active devices. Simulation results show that the inductor obtains a maximum Q-value of 1.2E8, an inductance value in the range of 50 nH to 450 nH, and a 1.4E-6 Omega of minimum total equivalent loss in the range of 0.6 GHz to 1.3 GHz.
