Patent ID: 7948014

Claim:
Electronic device having a semiconductor die comprising: at least one RF-transistor occupying a total RF-transistor active area on the die, the total RF-transistor active area including at least one transistor channel having a channel width and a channel length, and at least one bias cell for biasing the RF-transistor, the total bias cell having an active area including at least another transistor channel having another channel width and another channel length, the at least one bias cell occupying a total bias cell active area on the die; the total RF-transistor active area being substantially greater than the total bias cell active area, the total bias cell active area having a common centre of area, the total RF-transistor active area having a common centre of area, the active areas being arranged such that both, the common centre of area or sub-areas of the RF-transistor and the common centre of area or sub-areas of the bias cell are positioned on an axis, the axis being substantially perpendicular or parallel to the length of the at least one channel of the RF-transistor.
