A field transistor is divided into a number of cells (6) and includes a separate first gate line (20) connected to first transistor cells (8) and a separate second gate line (22) connected to second transistor cells (10). A drive circuit is used to drive all the cells (6) in a normal, saturated operations state but to drive only the second cells (10) in a linear operations state to reduce the number of cells used in the linear operations state.
