Abstract
A radio frequency switch made up of a plurality of switch cells coupled in series between a first node and a second node is disclosed. Each of the plurality of switch cells has a switch field-effect transistor (FET) having a switch drain terminal, a switch source terminal, a switch gate terminal, and a switch body terminal. A body bias network having a first body bias FET with a first drain terminal coupled to the switch body terminal includes a first cross-FET with a second drain terminal coupled to a first source terminal of the first bias body FET and a second source terminal coupled to the switch gate terminal. A second body bias FET has a third drain terminal coupled to the switch body terminal, and a second cross-FET has a fourth drain terminal coupled to a third source terminal of the second body bias FET.
