Abstract:
1. A differential RF power amplifier comprising: a first power amplifier, the first power amplifier having a first switching device coupled between a first supply voltage and a first node, and a second switching device coupled between a second node and a second supply voltage; a second power amplifier, the second power amplifier having a third switching device coupled between a third supply voltage and a third node, and a fourth switching device coupled between a fourth node and a fourth supply voltage; and an inductive network coupled to the first, second, third, and fourth nodes, wherein the inductive network includes a first inductor coupled between the first and second nodes such that current can flow between the first and second nodes through the first inductor and a second inductor coupled between the third and fourth nodes such that current can flow between the third and fourth nodes through the second inductor, wherein the first and second inductors each include one or more coils, and wherein the inductive network provides at least one inductor having one or more coils between any two of the first, second, third, and fourth nodes.
