CMOS Based Active Inductors: A Review
摘要
CMOS-based active inductors have gained attention as a viable substitute for conventional passive inductors in integrated circuit design. These active inductors capitalize on the benefits of CMOS technology, such as compact size, tunability, and seamless integration with other circuit elements. They also have drawbacks like excess power consumption, poor noise performance. To improve their performance, numerous topologies have been developed, each tailored to overcome specific challenges and meet diverse application needs. This review paper examines different topologies of active inductor on the basis of their design methodologies and performance metrices. A comparative analysis is presented, evaluating key parameters such as self-resonance frequency, inductance, quality factor, power consumption.
