A RADIO-FREQUENCY CMOS ACTIVE INDUCTOR AND ITS APPLICATION IN DESIGNING HIGH-Q FILTERS
An all-transistor CMOS active inductor with a selfresonance frequency fR = 5.7 GHz is presented. Large fR is achieved by forming an all-NMOS signal path. The measured quality factor, Q, is as high as 665, but Q can be infinite theoretically. Both fR and Q are tunable via biasing and on-chip varactors. As an example for using the active inductor, a high-Q bandpass filter for radiofrequency applications is designed. The inductor circuit was implemented in TSMC 0.18-μ m standard digital CMOS technology and occupies an area of 26.6 μ m × 30 μ m including double guardrings. For a supply voltage of 1.8 V, the circuit consumes 4.4 mW, and IIP3 is measured at Vpp = 270 mV.
