Monolithic integration of multiple compound semiconductor FET devices

A method for switching current using a control FET and a sync FET, the method comprising:

• partitioning a current into a plurality of current segments;
• distributing the plurality of current segments to sections of a control drain element of a control FET, the current segments distributed through a plurality of vias distributed along a surface of the control drain element;
• distributing the plurality of current segments to sections of a control source element of a control FET, the current segments distributed through a plurality of vias distributed along a surface of the control source element;
• coupling a control gate signal to a first and second end of a control gate finger disposed between the control drain element and a control source element of the control FET;
• switching the plurality of current segments from the control drain element to the control source element using the control gate finger;
• conducting the switched current segments along a continuous ohmic metal from the control source element of the control FET to a sync drain element of a sync FET;
• and
• extracting the plurality of current segments from sections along the sync drain element through a plurality of vias distributed along a surface of the sync drain element.
