Abstract:
1. A compensation network for a radiofrequency transistor comprising first and second bonding bars for coupling to a first terminal of the RF transistor and a compensation capacitor respectively; one or more bond wires coupling the first and second bonding bars together; and a compensation capacitor formed from a first set of conductive elements coupled to the second bonding bar, the first set of conductive elements interdigitating with a second set of conductive elements coupled to a second terminal of the RF transistor, wherein each of the second set of conductive elements is coupled to the RF transistor sequentially through a first single via, a first intermediate metal layer, a second set of vias, a second intermediate metal layer and a third set of vias, the first and second bonding bars are spaced apart to define a region for placement of the compensation capacitor, the compensation capacitor occupying substantially the entire region, characterised in that the first and second bonding bars are spaced apart by a predefined distance, the predefined distance being selected such that the bond wires have a desired inductance, wherein the first set of conductive elements and the second set of conductive elements are isolated from each other by a dielectric material.
