A CMOS 0.35 μm High Quality Factor Active Filter

35382

In this work we describe the topology of an active filter using active inductor principle with a high quality factor in CMOS technology. This filter shows a resonant frequency at 6.4 GHz. A negative resistor circuit and Qenhancement techniques such as channel width and current and voltage optimisation of the transistors compensated serial and parallel loss. S21 parameters were studied in two frequencies 6 GHz and 12 GHz according to the value of a capacitance that tunes the frequency of the filter.
