| 摘要 |
The invention relates to an electronic device having a semiconductor die comprising at least one RF-transistor (RFT) occupying a total RF-transistor active area (ARFT) on the die (DS). The total RF-transistor active area (ARFT) includes at least one transistor channel (C) having a channel width (W) and a channel length (L), and at least one bias cell (BC) for biasing the RF-transistor (RFT). The total bias cell active area (ABC) includes at least one transistor channel (C) having a channel width (W) and a channel length (L). The at least one bias cell (BC) occupies a total bias cell active area (ABC) on the die (SD). The total RF-transistor active area (ARFT) is substantially greater than the total bias cell active area (ABC). The total bias cell active area (ABC) has a common centre of area (COABC). The total RF-transistor active area (ARFT) has a common centre of area (COARF). The active areas (ABC, ARFT) are arranged such that both, the common centre of area or sub-areas of the RF-transistor (COARF) and the common centre of area or sub-areas of the bias cell (COABC) are positioned on an axis (AX2). The axis (AX2) is substantially perpendicular or parallel to the length (L) of the at least one channel (C) of the RF-transistor (RFT).
