A modified miniature 3D inductor to implement a fully‐integrated feedback wide band amplifier in a standard SiGe low cost 0.35 μm process is presented. According to the measurement results, the proposed technique achieves a 40% area reduction with minor performance degradation over the same circuit implemented with conventional inductors. The circuit provides a gain from 14 dB to 7 dB in the band between 3.1 GHz to 10.6 GHz. In the same band the noise figure (NF) varies from 2.9 dB to 4 dB. © 2010 Wiley Periodicals, Inc.
