Design of active RLC integrated filters with application in the GHz range

In this paper we discuss a method for making possible the active parallel-mode compensation of on-chip inductor and capacitor losses, and for making both the quality factor and the inductance value electronically tunable. The application of this technique in filters is emphasized throughout, and is demonstrated in a 2nd-order bandpass filter. The paper provides analytical results, discusses transistor-level circuits and presents experimental results from a linearity test on a breadboard.<<ETX>>
