Abstract :
This paper presents the design of a low power 3.5GHz analog programmable filter RFIC. The RF filter is a 7-tap transversal equalizer with cascaded Cherry-Hooper amplifiers for delay stages and Gilbert variable gain amplifier as tap weights. The delay stage using active devices greatly reduces the die area comparing to passive delay lines. The SiGe programmable filter RFIC consumes 250mW under 3.3V supply and occupies total 2.16mm2 die size
