Abstract
A radio frequency integrated circuit (RFIC) includes multi-finger transistors including discrete diffusion regions and interconnected within a reconfigured form factor as a single switch transistor. The RFIC also includes a source bus having a first plurality of source fingers coupled to each source region of the multi-finger transistors and a second plurality of source fingers orthogonally coupled to the first plurality of source fingers. The second plurality of source fingers couple the discrete diffusion regions in parallel. The RFIC also includes a drain bus having a first plurality of drain fingers coupled to each drain region of the multi-finger transistors and a second plurality of drain fingers orthogonally coupled to the first plurality of drain fingers. The second plurality of drain fingers electrically couple the discrete diffusion regions in parallel. The RFIC further includes a plurality of interconnected body contacts to bias a body of each of the multi-finger transistors.
