HIGH-Q INDUCTOR STRUCTURE

摘要

An inductor structure is provided to generate high quality factor and inductance at a high frequency using an active inductor structure of gyrator structure and a spiral inductor. A high-Q Inductor structure includes a feedback device which is inserted between a source part of transistor(M2) and a gate part of transistor(M1) in order to comprise a series-resonant circuit equivalent with a parasitic capacitance generated from the gate source part of both transistors(M1,M2). An active inductor which has a gyrator structure is composed of the transistors.
