Inductor-Less monolithic tunable active dual-band bandpass Filter

The inductor-less designing of monolithic tunable active dual-band bandpass filter is presented in this study. The center frequency and quality factor can be controlled via four biasing voltages. While the gain is constant, the center frequency shift is 200 MHz and quality factor can range from 60 to 180. We applied MMIC technology to design this filter. ED02AH technology is used to simulate the circuit elements. The power consumption of filter is 240 mW.
