Abstract
Illustrative embodiments of power amplifiers are disclosed. In one embodiment, a power amplifier includes a plurality of transistors formed on a silicon-on-insulator (SOI) substrate such that the plurality of transistors are each electrically isolated from one another within the SOI substrate. The power amplifier also includes a plurality of biasing networks, each biasing network being configured to dynamically bias at least one of the plurality of transistors. The plurality of transistors are electrically coupled in a series stack, with an output of the power amplifier being provided across the series stack.
Claims20
A power amplifier comprising:
- a plurality of transistors formed on a silicon-on-insulator (SOI) substrate such that the plurality of transistors are each electrically isolated from one another within the SOI substrate;
- and
- a plurality of biasing networks, each biasing network being configured to dynamically bias at least one of the plurality of transistors;
- wherein the plurality of transistors are electrically coupled in a series stack, an output of the power amplifier being provided across the series stack.
A differential power amplifier comprising:
- a first stack of series-connected, dynamically biased transistors formed on a silicon-on-insulator (SOI) substrate such that the transistors in the first stack are each electrically isolated from one another within the SOI substrate;
- a second stack of series-connected, dynamically biased transistors formed on the SOI substrate such that the transistors in the second stack are each electrically isolated from one another within the SOI substrate;
- and
- a plurality of inductors, each of the plurality of inductors coupling a node between a pair of transistors in the first stack to a corresponding node between a pair of transistors in the second stack.
