In this work a novel class AB tunable active filter with high linearity and high dynamic range is presented. It is based on a tunable active inductor (TAI) in class AB configuration with a very high quality factor and minimum power consumption. The class-AB operation is essential in many modern wireless applications and miniaturized systems and only few solutions have been presented in the literature in the past for the design of active inductors and filters, difficult to implement for commercial applications. Here, a solution with class-AB operation is addressed with circuit details. A prototype board has also been fabricated and tested, illustrating the feasibility for use in commercial applications and integrated solutions.
