This paper proposes a novel fully integrated digitally controlled active inductor for damping of ultrasonic transducer. Using new grounded inductor simulator (GIS) topology, the work addresses number of design challenges to demonstrate a feasibility of active damping of a transformer-less ultrasonic distance measurement sensor. The topology is described and basic parameters are derived in the paper. Presented GIS topology is suitable for full integration, and achieves low distortion, high input voltage dynamic range, and can digitally be tuned in a wide range from 1.1 to 75 mH with a step less than 1%. Presented design was manufactured in 0.18 um CMOS technology and occupies area of 0.216 mm2. Measurement results confirming key parameters are presented to support this work.
