A new structure of the on- chip integrated inductors im plem ented in conventional Si process is presented as a lateral solenoid.The fabrication process utilizes a conventional Si technology with standard double- layer m etal- lization.S param eters of the inductors based equivalent circuit are investigated and the inductor parameters are cal- culated from the m easured data.Experimental results are presented on an integrated inductors fabricated in a lateral solenoid type utilizing double m etal layers rather than a single metal layer as used in conventional planar spiral de- vices.Inductors with peak Q of 1.3and inductance value of 2 .2 n H are presented,which are com parable to conven- tional planar spiral inductors.
