    Abstract: The present disclosure describes aspects of a sub-device field-effect transistor architecture for integrated circuits. In some aspects, an integrated field-effect transistor (FET) is implemented with multiple FET sub-devices. During operation, source-side FET sub-devices of the integrated FET may operate in the linear region instead of in saturation. Operating in the linear region, the source-side FET sub-devices of the integrated FET may exhibit less threshold voltage or current sensitivity than other drain-side FET sub-devices that operate in saturation. A device layout of the integrated FET may be designed such that the less sensitive source-side FET sub-devices surround or protect the other more sensitive drain-side FET sub-devices from random variations or density issues at edges of the device layout. By so doing, a threshold voltage or current sensitivity of the integrated FET may be reduced, resulting in improved matching between integrated FET devices.
