  • Stacked field-effect transistor switch
    Patent number: 10749518
    Abstract: A stacked field-effect transistor (FET) switch is disclosed. The stacked FET switch has a first FET device stack that is operable in an on-state and in an off-state and is made up of a first plurality of FET devices coupled in series between a first port and a second port, wherein the first FET device stack has a conductance that decreases with increasing voltage between the first port and the second port. The stacked FET switch also includes a second FET device stack that is operable in the on-state and in the off-state and is made up of a second plurality of FET devices coupled in series between the first port and the second port, wherein the second FET device stack has a conductance that increases with increasing voltage between the first port and the second port.
