Claim Text:
1. A power cell designed for an RF power amplifier, comprising: a first MOSFET formed in a P-Well in a P-Substrate; a second MOSFET formed in an N-Well in the same P-Substrate, the second MOSFET having a vertical channel, a source node, a drain node, and a gate electrode, wherein the vertical channel is formed in the N-Well between the source node and the drain node with components of the gate electrode on left and right sides of the vertical channel, respectively, each of the components of the gate electrode being separated from the vertical channel by an oxide region, wherein components of the source node and the gate electrode are each arranged symmetrically on both sides of the drain node, respectively, to control current in the vertical channel in a vertical direction between the source node and the drain node and in a horizontal direction between the components of the gate electrode; wherein a source node of the first MOSFET and the source node of the second MOSFET are connected together to form the power cell.
