摘要：

In this work we present a pHMET single chip integrated active filter for high performances RF applications. The filter is based on a high-Q active inductor (AI) and is designed by the use of a single transistor for each resonator cell and a compensation net-work that allows controlling both the inductance value and its series resistance. The filter has been optimised for operating between 1800 MHz and 2100 MHz with a narrow 3 dB bandwidth of 30 MHz and a rejection ratio of 30dB at 30 MHz from the center frequency. The -8 dBm P1dB compression point and a dynamic range of 75 dB are obtained with a DC power consumption of 120 mW.
