SEMICONDUCTOR INDUCTOR USING TRANSISTOR TO IMPROVE INTEGRATION DEGREE

摘要

PURPOSE: A semiconductor inductor with wideband frequency range is provided to improve integration degree by forming the inductor using a transistor. CONSTITUTION: A first and second transistors(Q1,Q2) are connected in series between a first port(P1) and a second port(P2). A gate node of the first transistor is connected to the second port, and a gate node of the second transistor is connected to the first port through a tuning resistor(Rt). The transconductance of the second transistor is higher than that of the first transistor.
