In this paper, we present a systematic design procedure for Q-enhanced integrated LC filters, which does not require any simulations and is thus suitable for design automation. The design procedure has been described in the CAIRO+ analog design environment, containing the BSIM3v3 models of the MOS transistors. Precise estimations of the quality factor and the resonance frequency were made possible by adding the integrated inductance pi-model into the design environment. Several design examples of 2.4 GHz Q-enhanced LC filters are given in a 0.13 um CMOS process.
